Manage authentication realms in Proxmox

[lae]

By default pam and pve are realms created within Proxmox for authenticating users into Proxmox. This supports most use cases. However, Proxmox supports LDAP/AD realms, which some users may want:

This role should introduce a proxmox_realm (or something else) module to help manage and create these realms.

For new contributors:

There are existing modules in library/ that can be used for reference for this issue. The PVE API documentation is also available at https://pve.proxmox.com/pve-docs/api-viewer/.

I'd like to make a try with LDAP in the next months.

Hint for myself: pvesh get /access/domains
