Author: fidencio
 Title: #79: LIBSSS_CONFIG: Drop libsss_config
Action: opened

PR body:
"""
libssss_config has been used only by OpenLMI and the project has been
deprecated making, then, no sense to keep the support on SSSD.

Distros that, for some reason, are still packing and distributing
OpenLMI can stick to SSSD 1.14 branch.
