LDAP: Add the persistency for the "Enabled" property

This property will control that whether the LDAP service would
be started or not.

We are persisting this property using cereal, other properties
is being persisted through nslcd.conf, nslcd doesn't give us
a way to put this property under nslcd.conf.

Tested By:
      Test the persistency of enabled property.
        Verified that it was getting persisted across restart/reboot.
