[HUDI-7551] Avoid loading all partitions in CleanPlanner when MDT is enabled

[the-other-tim-brown]

Change Logs

This PR added a preloading from the MDT for the sake of performance but it also forces all the file group information into memory. This leads to higher memory usage than is required for the cleaner planner.

Changes in this PR:

• Adds new method to load a list of partitions
• Adds new endpoint for Remote FS View
• Removes old load-all call in the CleanPlanner constructor

Impact

Lowers amount of memory required for the cleaner planner

Risk level (write none, low medium or high below)

Low
