If a server with a CA has been marked as hidden and
contains the last A or AAAA address then that address
would remain in the ipa-ca entry.
This is because update-dns-system-records did not delete
values, it just re-computed them. So if no A or AAAA
records were found then the existing value was left.

The IPA location system relies on DNS record priorities in order to give
higher precedence to servers from the same location. For Kerberos, this
is done by redirecting generic SRV records (e.g.
_kerberos._udp.[domain].) to location-aware records (e.g.
_kerberos._udp.[location]._locations.[domain].) using CNAMEs.
This commit applies the same logic for URI records. URI location-aware
record were created, but there were no redirection from generic URI
records. It was causing them to be ignored in practice.
Kerberos URI and TXT records have the same name: "_kerberos". However,
CNAME records cannot coexist with any other record type. To avoid this
conflict, the generic TXT realm record was replaced by location-aware
records, even if the content of these records is the same for all
locations.

MIT KRB5 1.15 introduced KDC service discovery with URI records.
_kerberos and _kpasswd URI records can provide TCP, UDP, and Kerberos
KDC-Proxy references. URI lookups take precedence over SRV lookups,
falling back to SRV lookups if no URI records are found.
Also reduce TTL for system records from one day to one hour. It allows
users to remove or update discovery entries in a timely fashion.

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.

The method IPASystemRecords.get_locations_records() has a race condition.
The IPASystemRecords object creates a mapping of server names to server
data. get_locations_records() uses server_find() again to get a list of
servers, but then operates on the cached dict of server names.
In parallel replication case, the second server_find() call in
get_locations_records() can return additional servers. Since the rest of
the code operates on the cached data, the method then fails with a KeyError.
server_data is now an OrderedDict to keep same sorting as with
server_find().

Timeout 120 seconds is quite long and it makes uninstallation too long
for. Given that this is non critical operation and may be executed
manually later, waiting 120 seconds is too much. Usually waiting longer

__add_ca_records_from_hostname() now skips over DNS exceptions and
retries resolution until timeout of 120 seconds is reached.
Luckily current logic fails safe: In cases where resolution failed for
all the CA servers, the resulting zone object will not contain ipa-ca
record at all and the update logic will skip update for this name.
I.e. the original values in ipa-ca record set will be left in place.
