Fix a bug that when catalog is unified catalog the background refresh for hive connector do not work

Why I'm doing:

We found that when we use unified catalog the background refresh will not work.
Because that when we register into the map, we will use the same key.

What I'm doing:

Introduce a new object named ConnectorProcessorName and use this object as the key.
