Fix ipa-server-install for dual NICs

A server may have 2 or more NICs and its hostname may thus resolve
to 2 and more forward addresses. IP address checks in install
scripts does not expect this setup and may fail or crash.

This script adds a support for multiple forward addresses for
a hostname. The install scripts do not crash now. When one IP
address is needed, user is asked to choose from all detected
server IP addresses.
