Modify getInstanceByName to avoid calling getInstancesByNames

This PR modify getInstanceByname to loop through all management zones
directly instead of calling getInstancesByNames. Currently
getInstancesByNames use a node name prefix as a filter to list the
instances. If the prefix does not match, it will return all instances
which is very wasteful since getInstanceByName only query one instance
with a specific name.

Partially fix issue #42445
