make proxmox auto-provision user accounts on account creation and add them to a pool

[m]

pveum acl modify /pool/haylin-pool --roles Administrator --users haylin@devhack

pveum pool add haylin-pool

can do through proxmox json api (do we need a service account?) or through command line or through user.cfg

user:haylin@devhack:1:0::::::
pool:haylin-pool::::
acl:1:/pool/haylin-pool:haylin@devhack:Administrator:

although user should be created with a bunch of keycloak metadata like name & email:

user:haylin@devhack:1:0:haylin:moore:me@haylinmoore.com:::
