[Draft] Scopes support in auth commands

[tejaskochar-db]

(This PR is blocked on some changes in how the Go SDK stringifies scopes being picked up in the CLI. Tests will fail till then.)

Changes

• Updates the auth login command to take --scopes as an argument
• Updates the auth describe and auth profiles commands to also display scopes. They give a warning that validation of authentication may not work correctly when using scopes. This is because we validate by making calls requiring specific scopes which the user may not have requested.

Why

These changes come as part of an effort to support fine-grained, user-provided scopes in all our tools.

Tests

• unit tests
• acceptance tests
