[PATCH proxmox-backup v4 17/30] sync: push: optionally encrypt client log on upload if key is given

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

Encrypt the client log blob with given encryption key during syncs in push
direction, if given. The client log is not part of the manifest and therefore
needs to be handled separately.
