[PATCH proxmox-backup v3 19/23] notifications: Add XOAUTH2 parameters to endpoints

[Arthur Bied-Charreton <a.bied-charreton@proxmox.com>]

Add oauth2-client-secret and oauth2-refresh-token to POST and PUT
endpoints for SMTP notifications and pass them along to the
proxmox-notify functions.

The non-private parameters oauth2-client-id and oauth2-tenant-id are
passed as part of the SmtpConfig struct.
