Upgrade process to AM 13.x creates an OAuth2 Provider service to all realms

Upgrade process to AM 13.x creates an OAuth2 Provider service to all realms

Steps to reproduce

1.) Default installation of an AM12.0.3
2.) Deploy AM 13.5 or 13.0 and start container
3.) Hit the AM page and perform upgrade
4.) Go to "Top Level Realm" > Services

Observed result

OAuth2 Provider service is created. If you have more realm this service is created in all realms.

I tried create an OAuth2 Provider with my values in old AM and perform an upgrade and my values were NOT overwritten. I tested following properties:

• Authorization Code Lifetime (seconds)
• Refresh Token Lifetime (seconds)
• Access Token Lifetime (seconds)
• Issue Refresh Tokens:
• Issue Refresh Tokens on Refreshing Access Tokens
