* Fix of creating volumes from snapshots without backup
When few snaphots are created onyl on primary storage, and try to create
a volume or a template from the snapshot only the first operation is
successful. Its because the snapshot is backup on secondary storage with
wrong SQL query. The problem appears on Ceph/NFS but may affects other
storage plugins.
Bypassing secondary storage is implemented only for Ceph primary storage
and it didn't cover the functionality to create volume from snapshot
which is kept only on Ceph
* Address review
On newer libvirt/qemu it seems PCI hot-plugging could be an issue as
seen in:
https://www.suse.com/support/kb/doc/?id=000019383https://bugs.launchpad.net/nova/+bug/1836065
This was found to be true on ARM64/aarch64 platform (tested on
RaspberryPi4). As per the default machine doc, it advises to
pre-allocate PCI controllers on the machine and pcie-to-pci-bridge based
controller for legacy PCI models:
https://libvirt.org/pci-hotplug.html#x86_64-q35
This patch introduces the concept as a workaround until a proper fix is
done (ideally in the upstream libvirt/qemu projects). Until then client
code can add 32 PCI controllers and a pcie-to-pci-bridge controller for
aarch64 platforms.

* vxlan: arp does not work between hosts as multicast group is communicated over physical nic instead of linux bridge
when linux bridge is setup (refer to http://docs.cloudstack.apache.org/projects/archived-cloudstack-getting-started/en/latest/networking/vxlan.html#configure-product-to-use-vxlan-plugin) and used as the kvm traffic label of physical networks, the vms on different hosts cannot reach each other.
(1) does not work:
```
/usr/share/cloudstack-common/scripts/vm/network/vnet/modifyvxlan.sh -v 1001 -p eth1 -b brvx-1001 -o add
```
"bridge fdb" shows
```
00:00:00:00:00:00 dev vxlan1001 dst 239.0.3.233 via eth1 self permanent
```
(2) this works:
```
/usr/share/cloudstack-common/scripts/vm/network/vnet/modifyvxlan.sh -v 1001 -p cloudbr1 -b brvx-1001 -o add
```
"bridge fdb" shows

* vxlan: fix issue if kvm network label is not set
* Fix of some UEFI related issues
1 - fix of attach/detach ISO of VM with UEFI boot type
2 - if OS type of an ISO is categorized as "Other" the bus type of the disk
will be set to "sata"
* Simplify the validation of OS types
Datastore cluster as a primary storage support is already there. But if any changes at vCenter to datastore cluster like addition/removal of datastore is not synchronised with CloudStack directly. It needs removal of primary storage from CloudStack and add it again to CloudStack.
Here synchronisation of datastore cluster is fixed without need to remove or add the datastore cluster.
1. A new API is introduced syncStoragePool which takes datastore cluster storage pool UUID as the parameter. This API checks if there any changes in the datastore cluster and updates management server accordingly.
2. During synchronisation if a new child datastore is found in datastore cluster, then management server will create a new child storage pool in database under the datastore cluster. If the new child storage pool is already added as an individual storage pool then the existing storage pool entry will be converted to child storage pool (instead of creating a new storage pool entry)
3. During synchronisaton if the existing child datastore in CloudStack is found to be removed on vCenter then management server removes that child datastore from datastore cluster and makes it an individual storage pool.
The above behaviour is on par with the vCenter behaviour when adding and removing child datastore.
This PR fixes#4244
deploying of VMs from ISOs and from templates with UEFI boot type
deploying of VMs from ISOs and from templates with UEFI boot type with
volumes in RAW format
These changes are related to PR #3194, but include suspending/resuming the VM when doing a VM snapshot as well, when deleting a VM snapshot, as it is performing the same operations via Libvirt. Also, there was an issue with the UI/localization changes in the prior PR, as that PR was altering the Volume snapshot behavior, but was altering the VM snapshot wording. Both have been altered in this PR.
Issuing this in response to the work happening in PR #4029.
In previous cloudstack versions, qcow2 image does not have a backing file format.
however, it is required in newer qemu versions, for example qemu 4.2 on ubuntu 20.04.
steps to reproduce the issue
(1) install cloudstack 4.14 or previous version, and ubuntu 19.04 or 18.04/16.04 LTS.
(2) create vms.
(3) upgrade to 4.15, upgrade os to ubuntu 20.04 , or install a new server with ubuntu 20.04.
(4) migrate vm from old ubuntu version to ubuntu 20.04, failed with exception below

```
To make testing easier, step 1 and 2 can be replaced by
```
qemu-img create -f qcow2 -b <backing file> <qcow2 image>
```
so qcow2 image does not have a backing file format.

Add RBD main storage through UI, it will fail when there is no host port parameter;
Because when we created the pool, we did not add the port target in the xml

This PR fixes a regression issue in #4497
In cloudstack 4.14 or before, the cpu topology is set only when cpucore per socket is set (to 4 or 6).
in other conditions, there is no cpu topology in vm xml definition.
with #4497, vm will have cpu topology in its xml definition, if cpucore per socket is not set.
<topology sockets='<vm cpu cores>' cores='1' threads='1'/>
Not sure if it causes any issue. I think it would be better not to add this part in vm xml definition if cpucore per socket is not set.
Added property to agent.properties that enables or disables the iscsi session clean up feature. #4210
Added a condition to prevent disk partitions from being cleaned up. #4216
This is an extention of #3732 for kvm.
This is restricted to ovs > 2.9.2
Since Xen uses ovs 2.6, pvlan is unsupported.
This also fixes issues of vms on the same pvlan unable to communicate if they're on the same host
* DB : Add support for MySQL 8
- Splits commands to create user and grant access on database, the old
statement is no longer supported by MySQL 8.x
- `NO_AUTO_CREATE_USER` is no longer supported by MySQL 8.x so remove
that from db.properties conn parameters
For mysql-server 8.x setup the following changes were added/tested to
make it work with CloudStack in /etc/mysql/mysql.conf.d/mysqld.cnf and
then restart the mysql-server process:
server_id = 1
sql-mode="STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION,ERROR_FOR_DIVISION_BY_ZERO,NO_ZERO_DATE,NO_ZERO_IN_DATE,NO_ENGINE_SUBSTITUTION"
innodb_rollback_on_timeout=1
innodb_lock_wait_timeout=600
max_connections=1000
log-bin=mysql-bin
binlog-format = 'ROW'
default-authentication-plugin=mysql_native_password
Notice the last line above, this is to reset the old password based
authentication used by MySQL 5.x.
Developers can set empty password as follows:
> sudo mysql -u root
ALTER USER 'root'@'localhost' IDENTIFIED BY '';

This PR adds outputting human readable byte sizes in the management server logs, agent logs, and usage records. A non-dynamic global variable is added (display.human.readable.sizes) to control switching this feature on and off. This setting is sent to the agent on connection and is only read from the database when the management server is started up. The setting is kept in memory by the use of a static field on the NumbersUtil class and is available throughout the codebase.
Instead of seeing things like:

Ceph used to use port 6789 (no need to specify it), but with the messenger v2
from Ceph it switched to port 3300 while 6789 still works.
librados/librbd/libvirt will automatically figure out the ports to use if none is
specified.
Therefor there is no need for CloudStack to explicitely define the port in the XML
passed to Libvirt or Qemu.
Leave blank if no port number has been defined by the user.
When you migrate volume between data stores CS keeps the original UUID and changes the path of the volume.
When volume is not found by the given path the agent throws CloudRuntimeException but it's not catched in LibvirtGetVolumeStatsCommandWrapper.java
