Socket type resolution fails on ipv6 hostnames

[Amy Fong]

UDPPublisher tries to determine the IP version by attempting to do a netutils.is_valid_ipv6 test on the host part. In cases where the host is a hostname (as opposed to an IP addr), and in cases where this is an IPv6 address, netutils.is_valid_ipv6 fails and the constructor incorrectly determines that the address family is IPv4.

    Fix checking IP version when using IPv6.

    This commit fixes an issue with ceilometer incorrectly determining the
    IP version to use. Previously, it checked whether the hostname was a
    valid IPv6 address, but it should be resolving first to check whether
    that is a valid IP address instead.

    tests: Created test case that enables creating a UDPPublisher with
    hostname for ipv4 and ipv6.

    Closes-bug: #1616496
