[PATCH proxmox-backup v3 04/15] pbs-config: use proxmox-product-config::replace_config()

[Christian Ebner <c.ebner@proxmox.com>]

Instead of using the pbs-config local implementation, use the product
general implementation, dropping the local one instead.

Since proxmox-product-config::replace_config() requires the api- and
priv-user to be initialized a-priori, any calling codepath must
guarantee to have run proxmox-product-config::init() once.
