Title: #5174: Lookup ipa-ca record with NSS
DNS data management now uses NSS's getaddrinfo() instead of direct DNS
queries to resolve the ipa-ca record. This fixes missing ipa-ca records
when the current hostname is not resolvable in DNS but has correct
records in /etc/hosts.
Reduce timeout to 15 seconds and tighten timeout loop.
The changeset can speed up installation by almost 60 seconds.
ipa-server-install without built-in DNS calls into DNS data management
twice with a timeout of 30 seconds for each call.
