Subject: [PATCH] ipa-acme-manage: add certificate/request pruning management
Configures PKI to remove expired certificates and non-resolved
requests on a schedule.
This is geared towards ACME which can generate a lot of certificates
over a short period of time but is general purpose. It lives in
ipa-acme-manage because that is the primary reason for including it.
Random Serial Numbers v3 must be enabled for this to work.
Enabling pruning enables the job scheduler within CS and sets the
job user as the IPA RA user which has full rights to certificates
and requests.
Disabling pruning does not disable the job scheduler because the
tool is stateless. Having the scheduler enabled should not be a
problem.
A restart of PKI is required to apply any changes. This tool forks
out to pki-server which does direct writes to CS.cfg. It might
be easier to use our own tooling for this but this makes the
integration tighter so we pick up any improvements in PKI.
The "cron" setting is quite limited, taking only integer values
and *. It does not accept ranges, either - or /.
No error checking is done in PKI when setting a value, only when
attempting to use it, so some rudimentary validation is done.

+.SH "PRUNING"
+Pruning is a job that runs in the CA that can remove expired
+certificates and certificate requests which have not been issued.
+This is particularly important when using short-lived certificates
+like those issued with the ACME protocol. Pruning requires that
+the IPA server be installed with random serial numbers enabled.
+
+The CA needs to be restarted after modifying the pruning configuration.
+
+The job is a cron-like task within the CA that is controlled by a
+number of options which dictate how long after the certificate or
+request is considered no longer valid and removed from the LDAP
+database.
+
+The cron time and date fields are:
