* fix: change to generation script in manipulating googleapis/WORKSPACE.

* fix: mocked method in test needs to change after java.time introduced in gax.

* fix: address review comment, create a custom InstantiatingGrpcChannelProvider instead of using mocks.

* chore: use mvn wrapper in shocase test ci.

* address review comments.
