Change login flow to use Ory

[mpgxvii]

Description:

• Converts the management portal web app login to use the auth code login flow
• Adds support for Hydra oauth tokens by adding it as a JwksTokenVerifier
• Adds auth server (hydra) config
• Move all security config to SecurityConfiguration class and remove OAuth2ServerConfiguration class
• Removes unused security, config, and oauth classes

Fixes:

• https://github.com/RADAR-base/hydra-kratos/issues/19

Checklist:

• The Main workflow has succeeded
• The Gatling tests have passed
• I have logged into the portal running locally with default admin credentials
• I have updated the README files if this change requires documentation update
• I have commented my code, particularly in hard-to-understand areas

I think this means we can delete KratosTokenVerifierLoader

Probably good to do asap, or at least put it on a tasklist somewhere.

Otherwise, LGTM :)

The output of gradlew check does not show, but the test does not pass. Do you know why?
