[LU-11648] Create white list for CONFIGS directory files processing

Description

Not all files that are stored in CONFIGS directory should be processed. For example there are ".bak" files which created during change_nids operation and used to store non-modified copy. Currently blacklist is used to process CONFIGS directory (".bak"s are excluded), but using whitelist looks more robust.

Here is example of some MDT CONFIG directory list

# ls /mnt/fs2mdt/CONFIGS/
lustre-client   lustre-MDT0000  lustre-MDT0001  lustre-MDT0002  lustre-MDT0003  lustre-OST0000  lustre-OST0001  lustre-OST0002  lustre-OST0003  mountdata       nodemap         params       

params, node map, mountdata, client, *-MDT, -OST are allowed. What else?
