Use armeria-grpc client in storage-stackdriver.

[anuraaga]

One concern is the API change in storage-stackdriver's Builder not sure what the API guarantee on that is.

Only ran integration tests.

Fixes #119

[anuraaga]

Hmm - does the build require updating the license headers to 2019?

/cc @openzipkin/armeria

[codefromthecrypt]

we dont have api guarantees pre 1.0!

[codefromthecrypt]

looks great.

there might be a sneaky dep on grpc as I ran it and got a NCDFE

almost sorted

[codefromthecrypt]

ok this works now, except we have to bump zipkin's guava as grpc no longer works with guava 19. this requires a release of zipkin before the integration will work via curl downloading etc.

[anuraaga]

Man this is a lot of dependency hell...

[codefromthecrypt]

ok I tested against live stackdriver and all good

[codefromthecrypt]

thanks for the hard work @anuraaga!

[codefromthecrypt]

out at 0.11.0 (into the docker, too)

[trustin]

Nice work, @anuraaga !
