Add dynamic DNS updates to FreeIPA

This adds two new options:

ipa_dyndns_update: Boolean value to select whether this client
should automatically update its IP address in FreeIPA DNS.

ipa_dyndns_iface: Choose an interface manually to use for
updating dynamic DNS. Default is to use the interface associated
with the LDAP connection to FreeIPA.

This patch supports A and AAAA records. It relies on the presence
of the nsupdate tool from the bind-utils package to perform the
actual update step. The location of this utility is set at build
time, but its availability is determined at runtime (so clients
that do not require dynamic update capability do not need to meet
this dependency).
