* Introducing Storage Access Groups to define the host and storage pool connections
In CloudStack, when a primary storage is added at the Zone or Cluster scope, it is by default connected to all hosts within that scope. This default behavior can be refined using storage access groups, which allow operators to control and limit which hosts can access specific storage pools.
Storage access groups can be assigned to hosts, clusters, pods, zones, and primary storage pools. When a storage access group is set on a cluster/pod/zone, all hosts within that scope inherit the group. Connectivity between a host and a storage pool is then governed by whether they share the same storage access group.
A storage pool with a storage access group will connect only to hosts that have the same storage access group. A storage pool without a storage access group will connect to all hosts, including those with or without a storage access group.
Somehow deleteDatastore was never implemented, that meant:
templates haven't been cleaned up on datastore delete and
also agents have never been informed about storage pool removal.
If a -rst resource wasn't deleted because of a failed copy,
a reoccurring snapshot attempt couldn't be done, because there
was still the "old" -rst resource. To prevent this always
try to remove the -rst resource before, if it doesn't exist it is a noop.
This PR introduces the concept of multi-scope configuration settings. In addition to the Global level, currently all configurations can be set at a single scope level.
It will be useful if a configuration can be set at multiple scopes. For example, a configuration set at the domain level
will apply for all accounts, but it can be set for an account as well. In which case the account level setting will override the domain level setting.
This is done by changing the column `scope` of table `configuration` from string (single scope) to bitmask (multiple scopes).
```
public enum Scope {
Global(null, 1),
Zone(Global, 1 << 1),
Cluster(Zone, 1 << 2),
StoragePool(Cluster, 1 << 3),
ManagementServer(Global, 1 << 4),
ImageStore(Zone, 1 << 5),
Domain(Global, 1 << 6),
Account(Domain, 1 << 7);
```
Each scope is also assigned a parent scope. When a configuration for a given scope is not defined but is available for multiple scope types, the value will be retrieved from the parent scope. If there is no parent scope or if the configuration is defined for a single scope only, the value will fall back to the global level.
Hierarchy for different scopes is defined as below :
- Global
- Zone
- Cluster
- Storage Pool
- Image Store
- Management Server
- Domain
- Account
This PR also updates the scope of the following configurations (Storage Pool scope is added in addition to the existing Zone scope):
- pool.storage.allocated.capacity.disablethreshold
- pool.storage.allocated.resize.capacity.disablethreshold
- pool.storage.capacity.disablethreshold

Particular Linstor needs can use this information to only allow
dual volume access for live migration and not enable it in general,
which can and will lead to data corruption if for some reason
2 VMs get started on 2 different hosts.
If a node doesn't have a DRBD connection to another node,
additionally ask Linstor-Controller if the node is alive.
Otherwise we would have simply said no and the node might still be alive.
This is always the case in a non hyperconverged setup.

If a secondary storage pool is used by e.g.
2 concurrent snapshot->template actions,
if the first action finished it removed the netfs mount
point for the other action.
Now the storage pools are usage ref-counted and will only
deleted if there are no more users.
In non-hyperconverged setups, diskless nodes don't have a connection
to each other, so setting properties there had no effect.
Now it is checked if a connection exists,
between the live migration nodes and if not,
it will set the allow-two-primaries on resource-definition level.
qemu has a bug versions prior 7.0 with discard enabled and using the IDE bus.
It would crash the qemu process and kill the virtual machine,
this is most noticeable on installing a windows guest from the
Windows ISO installer.
* linstor: enable discard for Linstor storage pools
All Linstor storage backends support discard, so it can be safely enabled.
