Context

Is your feature request related to a problem? Please describe.
Support users can be anyone, and created during Dataset creation, and assigned by the data owner.

Describe the solution you'd like
In the dataset creation form, the support user can be anyone. This user does not currently get any elevate permissions and is cosmetic/informational only.
If the support user is not a YNet Active Directory user, they should have login disabled.
Only System admins should be able to "unlock" these accounts; or create the account as unlocked.

Describe alternatives you've considered
Might make sense to have all user information as text in the front-end dataset creation page, and only convert it to models in the back-end on submission? This might create potential issues around consistency.

Additional context

Should be consistent with #108
