[HBASE-20813] Remove RPC quotas when the associated table/Namespace is dropped off

• Type: Sub-task
• Status: Resolved
• Priority: Minor
• Resolution: Fixed
• Fix Version/s: 3.0.0-alpha-1, 2.2.0, 2.1.1, 2.0.2
• Labels: quota
• Hadoop Flags: Reviewed
• Release Note: In previous releases, when a Space Quota was configured on a table or namespace and that table or namespace was deleted, the Space Quota was also deleted. This change improves the implementation so that the same is also done for RPC Quotas.
