PR body: """ FreeIPA's Python and C code used different approaches to get the FQDN of the host. Some places assumed that gethostname() returns a FQDN. Other code paths used glibc's resolver to resolve the current node name to a FQDN.

Python code now uses the ipalib.constants.FQDN where a fully qualified domain name is expected. The variable is initialized only once and avoids potential DNS lookups.

C code uses a new helper function ipa_gethostfqdn() in util package. The function implements similar logic as gethostfqdn() except it uses more modern getaddrinfo(). The result is cached as well.
