Merge pull request #41682 from perotinus/unpwandtokens
Automatic merge from submit-queue (batch tested with PRs 41984, 41682, 41924, 41928) Add options to kubefed telling it to generate HTTP Basic and/or token credentials for the Federated API server fixes #41265. **Release notes**: ```release-note Adds two options to kubefed, `-apiserver-enable-basic-auth` and `-apiserver-enable-token-auth`, which generate an HTTP Basic username/password and a token respectively for the Federated API server. ```
