packaging - added check on firewall-cmd support

Added a check for --permanet option support for firewall-cmd.
If it's not supported, firewalld will not be available as
firewall manager.

Moved firewalld to global scope, the import will not fail
also if firewalld is not installed on the system.

core: Remove get image info call before images commands

BaseImageCommands calls for an image info updates its last modification
time on success and does nothing(!) on failure - the nothing is achieved
by updating the status in the DB and throwing an exception right
afterwards - which means a rollback to the update will be made.

also removed the unused VdcBllErrors.RESOURCE_MANAGER_VM_SNAPSHOT_MISSMATCH
