Implement hypervisor hostname exact pattern match
When starting cold migration with nova command "nova host- servers-migrate compute-1", the migration started from all compute hosts starting with name "compute-1", not only from compute-1 host. The same thing happens to "nova host-meta", "nova host-evacuate", "nova host-evacuate-live" as well. With the "--strict" option added to these nova commands, the action will be applied to a single compute with the exact hostname string match, but not to the computes with hostname substring match. Error handling is also added to these nova commands such that when specified hostname name does not exist, "NotFound" will be returned. Closes-Bug: #1667794 Change-Id: I5610efa160864b0d91cd67961883a6bec5bb8dd0
