This series adds Active Directory realm support to PBS, much like it
already exists in PVE. The logic matches it as closely as possible.

Patches #1 through #6 are purely preparatory. A lot of functionality
from the existing LDAP realm implementation can be re-used, esp. the
realm sync.

The API, authenticator and realm sync job implementations are partly
simply copied from LDAP, replacing structs and changing some things as
needed. The realm sync job simply reuses the existing LDAP
implementation for the most part, other than setting up some things

As for the UI, the existing panel for LDAP realms was also generic
enough such that it only needed a few conditionals as what input boxes
to show.

One thing to note is that - unlike PVE - you don't have to specify a
domain name when creating an AD realm. This is due to `proxmox-ldap`
already figuring out the correct, full DN of bind and login users
itself. That is the only use of the domain name in PVE anyway, thus it
is not present here.
The base DN is automatically determined from the `defaultNamingContext`
attribute of the root DSE object. It can be set manually in the config
if the need should arise. So that should be treated more like an
implementation detail.

I have tested this series using:

 * slapd 2.5.13+dfsg-5 as LDAP server to ensure no regressions
 * Samba 4.18.5 as an Linux-based AD server and
 * AD on Windows Server 2022 to make sure that works as well

For slapd and MS AD, I tested both anonymous binds and authenticated
binds, with Samba only authenticated binds (since there seems to way to
turn on anonymous binds in Samba, at least that I could find ..) as well
as dry-running and actual syncing of users. Further, then also logging
into PBS with a sync'd user.
