[pdm-devel] [PATCH proxmox-datacenter-manager 04/16] api: sdn: add create_zone endpoint

[Stefan Hanreich <s.hanreich@proxmox.com>]

This endpoint is used for creating a new EVPN zone on multiple
remotes. It utilizes the newly introduced LockSdnClients helper for
performing the action simultaneously across all remotes and rolling
back in case of failure.
