[ISSUE] inconsistent naming of user between identity external DB and webmodeler restapi external DB

[hamza-m-masood]

Describe the issue:

The user is defined like this for identity, and webmodeler:
identity.externalDatabase.username
webModeler.restapi.externalDatabase.user

The naming is inconsistent. It would be better to have user for both, since that would align with Keycloak.

This would result in a breaking change.

• Deprecate username?
• And align on keycloaks settings using .user
• Postgres uses .username

How should our convention look like?

[hamza-m-masood]

Since we are moving away from keycloak in the future, we can stick to the convention used by Postgres and use .username
