In the migration case of replica installation, if the CA server is
an older version it may not support the ipa-ca.$DOMAIN dnsName in
the HTTP cert (it is a special case in the cert_request command).
Therefore if the request fails, try it again without the
ipa-ca.$DOMAIN dnsName.

BACKGROUND:
We are implementing ACME support in FreeIPA (umbrella ticket:
https://pagure.io/freeipa/issue/4751). ACME is defined in RFC 8555.
HTTPS is REQUIRED (https://tools.ietf.org/html/rfc8555#section-6.1).
Therefore, every FreeIPA server that provides the ACME service
capability must be reachable by HTTPS.
RFC 8555 does not say anything about which port to use for ACME.
The default HTTPS port of 443 is implied. Therefore, the FreeIPA
ACME service will be reached via the Apache httpd server, which will
be the TLS server endpoint.
As a usability affordance for ACME clients, and as a maintainability
consideration i.e. to allow the topology to change without having to
reconfigure ACME clients, there should be a a single DNS name used
to reach the IPA ACME service.
The question then, is which DNS name to use.
REQUIREMENTS:
Each FreeIPA server that is also an ACME server must:
1. Be reachable via a common DNS name
2. Have an HTTP service certificate with that DNS name as a SAN
dNSName value
DESIGN CONSIDERATION - WHAT DNS NAME TO USE?:
Some unrelated FreeIPA ACME design decisions provide important
context for the DNS name decision:
- The ACME service will be automatically and unconditionally
deployed (but not necessarily *enabled*) on all CA servers.
- Enabling or disabling the ACME service will have topology-wide
effect, i.e. the ACME service is either enabled on all CA
servers, or disabled on all CA servers.
In a CA-ful FreeIPA deployment there is already a DNS name that
resolves to all CA servers: ``ipa-ca.$DOMAIN``, e.g.
``ipa-ca.example.com``. It is expected to point to all CA servers
in the deployment, and *only* to CA servers. If internal DNS is
deployed, the DNS records for ``ipa-ca.$DOMAIN`` are created and
updated automatically. If internal DNS is not deployed,
administrators are required to maintain these DNS records
themselves.
The ``ipa-ca.$DOMAIN`` alias is currently used for OCSP and CRL
access. TLS is not required for these applications (and it can
actually be problematic for OCSP). Enabling TLS for this name
presents some risk of confusion for operators. For example, if they
see that TLS is available and alter the certificate profiles to
include an HTTPS OCSP URL in the Authority Information Access (AIA)
extension, OCSP-using clients may fail to validate such
certificates. But it is possible for administrators to make such a
change to the profile, whether or not HTTPS is available.
One big advantage to using the ``ipa-ca.$DOMAIN`` DNS name is that
there are no new DNS records to manage, either in the FreeIPA
implementation or for administrators in external DNS systems.
The alternative approach is to define a new DNS name, e.g.
``ipa-acme.$DOMAIN``, that ACME clients would use. For internal
DNS, this means the FreeIPA implementation must manage the DNS
records. This is straightforward; whenever we add or remove an
``ipa-ca.$DOMAIN`` record, also add/remove the ``ipa-acme.$DOMAIN``
record. But for CA-ful deployments using external DNS, it is
additional work for adminstrators and, unless automated, additional
room for error.
An advantage of using a different DNS name is ``ipa-ca.$DOMAIN`` can
remain inaccessible over HTTPS. This possibly reduces the risk of
administrator confusion or creation of invalid AIA configuration in
certificate profiles.
Weighing up the advantages and disadvantages, I decided to use the
``ipa-ca.$DOMAIN`` DNS name.
DESIGN CONSIDERATION - CA SERVERS, OR ALL SERVERS?:
A separate decision from which name to use is whether to include it
on the HTTP service certificate for ACME servers (i.e. CA servers)
only, or on all IPA servers.
Combined with the assumption that the chosen DNS name points to CA
servers *only*, there does not seem to be any harm in adding it to
the certificates on all IPA servers.
The alternative is to only include the chosen DNS name on the HTTP
service certificates of CA servers. This approach entails some
additional complexity:
- If a non-CA replica gets promoted to CA replica (i.e. via
``ipa-ca-install``), its HTTP certificate must be re-issued with
the relevant name.
- ipa-server-upgrade code must consider whether the server is a CA
replica when validating (and if necessary re-creating) Certmonger
tracking requests
- IPA Health Check must be made aware of this factor when checking
certificates and Certmonger tracking requests.
Weighing up the options, I decided to add the common DNS name to the
HTTP service certificate on all IPA servers. This avoids the
implementation complexity discussed above.
CHANGES IN THIS COMMIT
When (re-)tracking the HTTP certificate, explicitly add the server
FQDN and ipa-ca.$DOMAIN DNS names to the Certmonger tracking request.
Related changes follow in subsequent commits.

We need to be able to filter Certmonger tracking requests by the DNS
names defined for the request. The goal is to add the
'ipa-ca.$DOMAIN' alias to the HTTP certificate tracking requests, so
we will use that name as a search criterion. Implement support for
this.
As a result of this commit it will be easy to add support for subset
match of other Certmonger request list properties. Just add the
property name to the ARRAY_PROPERTIES list (and update the
'criteria' description in the module docstring!)

When running on memory-constrained systems, the `ipa-server-install`
program often fails during the "Configuring certificate server
(pki-tomcatd)" stage in FreeIPA 4.5 and 4.6.
The memory-intensive dogtag service causes swapping on low-memory
systems right after start-up, and especially new certificate
operations requested via certmonger can exceed the dbus client default
25 second timeout.
This patch changes dbus client timeouts for some such operations to
120 seconds (from the default 25 seconds, IIRC).
