This is a roll-forward of 5b865f1, with the QueueDeclare and QueueBind changes
in AMQP-RPC removed, and the startup order changes in test/startservers.py
removed. The AMQP-RPC changes caused RabbitMQ permission problems in production,
and the startup order changes depended on the AMQP-RPC changes but were not
required now that we have a unittest also.
This allows us to restart backends with relatively little interruption in
service, provided the backends come up promptly.
Fixes#2389 and #2408
Previously we had custom code in each gRPC wrapper to implement timeouts. Moving
the timeout code into the client interceptor allows us to simplify things and
reduce code duplication.
Based on experience with the new gRPC staging deployment. gRPC generates `FullMethod` names such as `-ServiceName-MethodName` which can be confusing. For client calls to a service we actually want something formatted like `ServiceName-MethodName` and for server requests we want just `MethodName`.
This PR adds a method to clean up the `FullMethod` names returned by gRPC and formats them the way we expect.
Fixes#1880.
Updates google.golang.org/grpc and github.com/jmhodges/clock, both test suites pass. A few of the gRPC interfaces changed so this also fixes those breakages.
Adds a server side unary RPC interceptor which includes basic stats. We could also use this to add a server request ID to the context.Context to identify the call through the system, but really I'd rather do that on the client side before the RPC is sent which requires the client interceptor implementation upstream. Also updates google.golang.org/grpc.
Updates #1880.
