Avoid LDAP lookups for local groups

Currently we see LDAP lookups for all local groups with openLDAP
and Active Directory configuration.

this commit updates config with "nss_initgroups_ignoreusers ALLLOCAL"
this option filters out all LDAP lookups for all local groups.

update LDAP config with nss_initgroups_ignoreusers ALLLOCAL
while creating configuration for openLDAP and active directory.
