When dumping XML use appropriate flags:
1, VIR_DOMAIN_XML_SECURE (dump security sensitive information too)
8, VIR_DOMAIN_XML_MIGRATABLE (dump XML suitable for migration)

This fixes CVE 2015-3252: VNC password lost during VM migration across KVM
hosts. The issue is also seen when a VM is rebooted.

We don't need an external script to investigate the format of the RBD volume,
we only have to ask Libvirt to resize the volume and that will ask librbd to
do so.
Backport for 4.4, original commit: 173909e99d
CentOS 7 does not ship with ifconfig anymore. We should use ip commands instead.
This also works on older versions, like CentOS 6 and Ubuntu 12.x/14.x, that we
support.
This closes#165

Earlier host addition of multiple hosts with local storage failed due to
same local storage UUID being used where the storage path is same.

KVMStoragePoolManager is a singleton in practice, any plugin
or extension of LibvirtComputingResource will need to act on
the specific instance of KVMStoragePoolManager that LibvirtComputingResource
has initialized. Therefore, expose this variable for those who
wish to call storage commands from plugins or extensions.

In situations where libvirt lost the storage pool the KVM Agent will re-create the
storage pool in libvirt.
This could be then libvirt is restarted for example.
The object returned internally was missing essential information like the sourceDir
aka the Ceph pool, the monitor IPs, cephx information and such.
In this case the first operation on this newly created pool would fail. All operations
afterwards would succeed.
This patch is for KVM
1. Local testing on KVM
2. Successfully got up system VMs
3. Successfully created a CentOS VM
4. Snapshots are not supported for KVM

Since we use qemu-img to copy from RBD to Secondary Storage we no
longer have to force to RAW images, but can stick with QCOW2
When the snapshot backups are QCOW2 format they can easily be deployed
again when restoring from a backup

Added a new flag 'checkBeforeCleanup' to StopCommand based on which check is done to see if VM is running in HV host.
If VM is running then in this case it is not stopped and the operation bails out.
Also modified the MS code to call the StopCommand with appropriate value for the flag based on the context.
Currently it is only set to 'true' when called from the new vmsync logic based on powerstate of VM. For rest it
is set to 'false' meaning no change in behaviour.
This reduces the amount of time and storage it takes dramatically. We no longer
do a full copy, but a sparse copy. The destination image is still in RAW
format, but we only copy over used blocks.
Qemu is also better in doing this then us doing it in Java code.
This saves the step of writing to a temporary image in /tmp first before
writing to RBD.
This is possible due to a new version in librbd. With the rbd_default_format
setting we can now force qemu-img to create format 2 RBD images.
This is available since Ceph version 0.67.5 (Dumpling).
Otherwise a RBDException will be thrown with the message that the snapshot
isn't protected.

Add executeInVR() with timeout interface to VirtualRouterDeployer
AggregationControlCommand with Action.Finish may take longer than normal command
since it would execute all the commands in one execution, and it may result in
SSH timeout for SshHelper or other mechanism communicate with VR.
Introduce an new executeInVR() interface with added timeout period for waiting
FinishAggregationCommand to complete execution.
- get the hosts on which VPC spans given vpc id
- get the VM's in the VPC
- get the hosts on which a network spans
- get the VPC's to which a hosts is part of
- get VM's of a VPC on a hosts
introduces capability to build a physical toplogy representation of a
VPC. This json file is encapsulated in
OvsVpcPhysicalTopologyConfigCommand, and is used to send full topology
to hypervisor hosts. On hypervisor this json config can be used to setup
tunnels, configure bridge, add flow rules etc
Ovs GURU, to use different broasdcast scheme VS://vpcid.gerkey for the
networks in VPC that use distributed routing
each VIF and tunnel interface to carry the network UUID in other/options
config
2) Corrected some logging in MidoNetPublicNetworkGuru - removed .toString method call on the objects in the log body as toString is called on the object by default when use log4j
