Move Play gRPC tests into Play repos

[richdougherty]

Once we're happy that the test APIs created in #356 and #361 are stable we'll want to move these tests into Play repositories. Some code will be moved into playframework/playframework, some into playframework/scalatestplus-play and some could move into a new repository like playframework/play-grpc. For now we can leave the code in the akka-grpc repository, since it's easier to develop it within a single repository.

Note that PR #356 adds some notes in the source that should be addressed when working on this issue. The notes from me are tagged // RICH:, so a grep should find them.

See: #356 (comment)

(reopened since automatically closed, probably we can remove some code from this repo once the next version of play is released?)

[dwijnand]

Closing was intentional. But I'm happy to track the removal here with this. 👍

TIL GitHub will handle cross-project (cross-organization) PR-related events on issues.

Provided you have write permission to the issue, yes.

Once Play 2.7 M4 is out this can be finished off.

[dwijnand]

With playframework/scalatestplus-play#123 merged, this is blocked on a fresh cut of scalatestplus-play.

[dwijnand]

With #439 merged, this is now blocked on a fresh cut of akka-grpc.

This is the last step. Move everything to do with Play out of this repo, into play-grpc, including play-interop-test-java, play-interop-test-scala, generators and any other tests.
