core: change retention policies to CLASS

jyane · ejona86 · commit 0c210322216b · 2018-01-26T13:01:55.000-08:00
`@Internal` and `@ExperimentalApi` annotations are not visible at compile time
of application (not grpc-java) because their retention policies are `SOURCE`.
So, change retention policies to `CLASS`.
