Doc Text:	.Admin socket command to invalidate cache Two new admin socket commands to manipulate the cache were added to the `radosgw-admin` tool. The `cache erase <objectname>` command flushes the given object from the cache. The `cache zap` command erases the entire cache. These commands can be used to help debug problems with the cache or provide a temporary workaround when an RGW node is holding stale information in the cache. Administrators can now flush any and all objects from the cache.	Story Points:	---
