The original implementation had a few issues:
* The secret was briefly leaked since it is part of the cmdline for
`sed(1)` and on Linux `cmdline` is world-readable.
* If the secret would contain either a `,` or a `"` it would mess with
the `sed(1)` expression itself unless you apply messy escape hacks.
To circumvent all of that, I decided to use `replace-secret` which
allows you to replace a string inside a file (in this case
`#static-auth-secret#`) with the contents of a file, i.e.
`cfg.static-auth-secret-file` without any of these issues.
Lego has a built-in mechanism for sleeping for a random amount
of time before renewing a certificate. In our environment this
is not only unnecessary (as our systemd timer takes care of it)
but also unwanted since it slows down the execution of the
systemd service encompassing it, thus also slowing down the
start up of any services its depending on.
Also added FixedRandomDelay to the timer for more predictability.

Check if an actual key file exists. This does not
completely cover the work accountHash does to ensure
that a new account is registered when account
related options are changed.
Fixes#191794
Lego threw a permission denied error binding to port 80.
AmbientCapabilities with CAP_NET_BIND_SERVICE was required.
Also added a test for this.
`privacyidea-token-janitor`[1] is a tool which helps to automate
maintenance of tokens. This is helpful to identify e.g. orphaned tokens,
i.e. tokens of users that were removed or tokens that were unused for a
longer period of time and apply actions to them (e.g. `disable` or
`delete`).
This patch adds two new things:
* A wrapper for `privacyidea-token-janitor` to make sure it's executable
from CLI. To achieve this, it does a `sudo(8)` into the
`privacyidea`-user and sets up the environment to make sure the
configuration file can be found. With that, administrators can
directly invoke it from the CLI without additional steps.
* An optional service is added which performs automatic cleanups of
orphaned and/or unassigned tokens. Yes, the tool can do way more
stuff, but I figured it's reasonable to have an automatic way to clean
up tokens of users who were removed from the PI instance. Additional
automation steps should probably be implemented in additional
services (and are perhaps too custom to add them to this module).
