Refactor authconfig use in ipa-client-install

When certain features are being configured via authconfig, we need to
remember what was configured and what was the state before it so that
during uninstall we restore proper state of the services.

Mostly it affects sssd configuration with multiple domains but also
pre-existing LDAP and krb5 configurations.

This should fix following tickets:
