LDAP: Move the ldap enum request to its own reusable module

The LDAP enumeration was too closely tied to the LDAP identity provider.
Because some providers might need special handling such as refresh the
master domain record before proceeding with the enumeration itself, this
patch splits the request itself to a separate async request and lets the
ldap_id_enum.c module only configure this new request.

Also move the enum timestamp to sdap_domain to make the enum tracking
per sdap domain. The cleanup timestamp will be moved in another patch.
