feat(APIKeys: (67) Added API Key UI

[JEFFTheDev]

Some thoughts:

• Maybe we need to discuss some standardized way of form validation now that we're adding more user generated content features. Currently I've used the snackbar which works fine but best practice might be to have some error messages in the form itself
• In this PR I chose to have the frontend self-service be a seperate running go program, as discussed this will be changed to be served from a seperate port but still be available from the same program. When our UIs merge we will fix this, same goes for the generic layout package.
