[LU-17137] Deprecate l_getidentity files alias

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.16.0

Description

Historically l_getidentity 'lookup files' masks the nss 'files' module in favor the passws/group files in /etc/lustre.

Deprecate the use of 'files' where 'lustre' is preferred in preparation of removing the alias.
