dyndns: New option dyndns_update_ptr

https://fedorahosted.org/sssd/ticket/1832

While some servers, such as FreeIPA allow the PTR record to be
synchronized when the forward record is updated, other servers,
including Active Directory, require that the PTR record is synchronized
manually.

This patch adds a new option, dyndns_update_ptr that automatically
generates appropriate DNS update message for updating the reverse zone.

This option is off by default in the IPA provider.

Also renames be_nsupdate_create_msg to be_nsupdate_create_fwd_msg
