This has been additionally verified by running the tests locally as a
basic smoke test. GitHub Actions doesn't provide MacOS M1 (arm64) yet,
so there's no good way to automate testing.
Ran `TMPDIR=/tmp make test` locally. The `TMPDIR` bit is needed so
there's no really long path used that breaks Unix socket setup in one of
the tests.

- Moves grpcproxy & functional tests to a separate workflows such thay can get restarted independently.
- Configures travis to run 1.16.3 go version (as travis cannot resolve 1.16 to the default).
