 Title: #2041: [Backport][ipa-4-5] Sort and shuffle SRV record by priority and weight
Action: opened

PR body:
"""
On multiple occasions, SRV query answers were not properly sorted by
priority. Records with same priority weren't randomized and shuffled.
This caused FreeIPA to contact the same remote peer instead of
distributing the load across all available servers.

Two new helper functions now take care of SRV queries. sort_prio_weight()
sorts SRV and URI records. query_srv() combines SRV lookup with
sort_prio_weight().

PR was ACKed manually because this is backport of PR #2032.
