More detailed description of your change, if necessary. The PR title and PR message become the squashed commit message, so use a separate comment to ping reviewers.

Support --release in FeatureCommand, currently, we only have one feature which is metadata.version.

Summary of testing strategy (including rationale) for the feature or bug fix. Unit and/or integration tests are expected for any behaviour change and system tests should be considered for larger changes.

Added a test case in FeatureCommandTest

@mumrah Thank you for your reminder, I added --release support for describing and added a unit test for it.

[dengziming]

@mumrah Do we still need --release after we add --metadata? I will close this if it's unnecessary or rebase this PR onto trunk if it's still useful.

[dengziming]

Closing this since we are using --metadata instead of --release.
