Feature scope

CLI (options, error messages, logging, etc.)

Description

After the UI and API were removed, some tables became redundant:

• embed_tokens
• oauth
• subscriptions
• role_permissions
• roles_users
• user

If Meltano has no further use for these, they should probably be removed so the database migration scripts don't attempt to create them. This might make it easier for other database systems to be supported out-of-the-box, for example:

• feature: Support for MySQL as a backend database #6529 (comment)
• feature: support Snowflake as database backend #8761
