[BUG][Tiered cache] Removal on EhcacheDiskCache key iterator doesn't work #12652
Description
Describe the bug
EhcacheDiskCache exposes a way to iterator over keys which is basically a wrapper over underlying ehcache iterator. Link
If we try to call iterator.remove() on above iterator, it won't work as it isn't supported.

To Reproduce
Write a simple unit test on EhcacheDiskCacheTests, fetch iterator and call remove(). Try to assert that the key actually got removed.
Expected behavior
Calling remove() on EhCacheKeyIterator should be able to remove the desired key.
For fix, we need to override remove() in above class.
