Extend oidc_cli security context generator to include calls to the v2…

[LGhoull]

Thank you for contributing to Harbor!

Comprehensive Summary of your change

• Extend oidc_cli security context generator to include calls to the v2 API
• remove idtoken security context generator
• rename and consolidate tests and names accordingly

Id Tokens can no longer be used to authenticate against the v2 API
Instead, basic auth with the CLI secret as password must be used.

The use of the OIDC ID token as a bearer token for authentication against the API is inconvenient since the ID token is hard to get as a normal user.

Definitely a breaking change, but I can't add labels.

[reasonerjt]

Although the change is relatively small, b/c this is a break change and involves security. I wish to suggest that a proposal is needed for review and get approval from maintainers.

If we reach a consensus to do this, there should also be some change needed in UI and Documentation.

[reasonerjt]

Please write a proposal and get approval first.
