Support disabling host verification in naming service

As a workaround for an issue found in processing SAN certificates,
allow for hostname verification to be diabled by setting the
environment variable DISABLE_HOST_VERIFICATION=true.  By default,
host name verification remains enabled ... it must be explicitly
disabled for this environment variable setting.
