This reverts commit 55d5027c97.
Reason for revert: the process_resident_memory_anonymous_bytes and process_resident_memory_pagecache_bytes metrics have been substituted
by more complete set of metrics in the commit 5a49bb8e88:
* process_resident_memory_anon_bytes
* process_resident_memory_file_bytes
* process_resident_memory_shared_bytes
