chore!: set Cloudian Group and User ids from Crossplane external-name

[erikgb]

Cloudian GroupId seems like an "external name" to me, and using the Crossplane external-name ensures that we don't get any confusion in the mapping between Crossplane and Cloudian.

Time to implement selector in

provider-cloudian/apis/user/v1alpha1/user_types.go

Line 30 in 0ad9b9b

GroupID string `json:"groupId"`

then?

And externalname in

provider-cloudian/apis/user/v1alpha1/user_types.go

Line 31 in 0ad9b9b

UserID string `json:"userId"`

as well?
