1a2cd7f408 Use datetime.timezone.utc instead of newer datetime.UTC alias
datetime.UTC alias was added in Python 3.11:
https://docs.python.org/3/library/datetime.html#datetime.UTC

datetime.timezone.utc was present since Python 3.2.

Since RHEL 9 is using Python 3.9, use more compatible variant.

59e68f79e4 ipa-epn: include timezone info
ipa-epn is using timezone-aware timestamps for "now"
but converts krbpasswordexpiration attribute into
a naive datetime object that is missing the tzinfo.

It is not possible to substract timezone aware and
naive values. Convert krbpasswordexpiration attribute
into an UTC value before doing the substration.

17f430efc4 EPN: Allow authentication by SMTP client's certificate
SMTP server may ask or require client's certificate for verification.
To support this the underlying Python's functionality is used [0].

Added 3 new options(corresponds to `load_cert_chain`):
- smtp_client_cert - the path to a single file in PEM format containing the
  certificate.
- smtp_client_key - the path to a file containing the private key in.
- smtp_client_key_pass - the password for decrypting the private key.

4758db121e Simplify determining if IPA client configuration is complete
When asking the quesiton "is my IPA client configured?" right now
we look at whether the installation backed up any files and
/etc/ipa/default.conf exists.

Instead set a new state, installation, to True as soon as the
client installation finishes.

Unlike the server there is no upgrade process for clients so this
isn't going to be all that useful for quite some time unless that
changes because upgrading an existing install won't set this
to True.

03caa7f965 Add a jinja2 e-mail template for EPN
Add options for character set (default utf8) and message
subtype (default plain). This will allow for more control
for users to do either HTML mail or use ascii for the character
set so the attachment is not base64-encoded to make it easier
for all mail clients.

Collect first and last name as well for each user in order to
provide more options for the template engine.

Make the From address configurable, defaulting to noreply@ipa_domain
Make Subject configurable too.

Don't rely on the MTA to set Message-Id: set it using the email
module.

b8886c3e97 IPA-EPN: First version.
EPN stands for Expiring Password Notification. It is a standalone
tool designed to build a list of users whose password would expire
in the near future, and either display the list in a machine-readable
format, or send email notifications to these users.

EPN provides command-line options to display the list of affected users.
This provides data introspection and helps understand how many emails
would be sent for a given day, or a given date range.
The command-line options can also be used by a monitoring system to alert
whenever a number of emails over the SMTP quota would be sent.

EPN is meant to be launched once a day from an IPA client (preferred)
or replica from a systemd timer.

EPN does not keep state. The list of affected users is built at runtime
but never kept.

TLS/STARTTLS SMTP code is untested and unlikely to work as-is.
