SUMMARY
Merge existing proxmox_pool and proxmox_pool_member into one module proxmox_pool.
So by adding managing members functionality to proxmox_pool and marking proxmox_pool_member as deprecated or adding a mark which indicates to prefer to use proxmox_pool.
This will match the PVE API and be more convenient to manage pool configuration.
