It was implemented by extending the NFS provider. Its validation was updated so that you can pass it a URL containing the
details of a CIFS share. The code that mounts NFS shares was extended to allow it do the same for CIFS shares. Otherwise,
the secondary storage code is left unchanged.
Issue happens as there are more than one thread processing connect for a host simultaneously. The VM full sync. is not designed to work in this scenario and as a result user VMs may get stopped incorrectly.
Direct agent scan task runs at regular intervals (direct.agent.scan.interval defaulted to 90 secs) and identifies hosts that needs to be processed for connect. In a normal scenario hosts mostly get connected within that interval and there are no issues. But if due to some reason the connect process takes more time and is not completed by the time next agent scan runs. In this case, based on the db. state same hosts may get picked up again. And then there will be situations where more than one thread is processing connect for the same host.
The fix is to check if there is a thread already processing connect for a host and in this case all subsequent threads for that host will simply bail out. Also there may be a scenario where one thread already completed processing connect but another thread already got scheduled before that and will again repeat the same. This is also prevented by putting appropriate checks.
Check for the all the transition states for Maintenance. Also corrected the isMaintenance function for StoragePoolVo

Description:
Set the criterion for overriding/preserving the vmware.create.full.clone
flag so that if past version deployments have any deployments (data centers),
this flag will be set to false. Else, it will be set to true.
The earlier criterion to set this flag was based on the CS version numbers,
but that is not a good business logic to serve as a basis to set the flag.
Changes:
- In the upgrade path, for a private zone, entry needs to be added in the affinity_group_domain_map to provide access to the private zone for the domains it belongs too.
Changes:
- Implict creation of the 'ExplicitDedication' Affinity group during resource dedication
- Only one group per account or per domain will be present
- ListDedicatedResources by affinityGroup
- Deployment should consider dedicated resources associated to the group only
- Deleting affinity group should release the dedicated resouces
- Releasing the dedicated resources should remove the group associated if there are no more resources.

Changes:
- 'ExcplicitDedication' type of group can be created/deleted by Root admin only
- Users can no longer create this type of affinity group
- RootAdmin can create this type of affinitygroup at domain level. Such a domain level group is available for all accounts in that domain for listing and for use during deployVM.
- The domain level affinitygroup should be visible to the users in that domain, domain admins and Root admin.
