Seth Hoenig f2ef576510 demo: create a demo service for grpc healthchecks

Examples for HTTP based task-group service healthchecks are
covered by the `countdash` demo, but gRPC checks currently
have no runnable examples.

This PR adds a trivial gRPC enabled application that provides
a Service implementing the standard gRPC healthcheck interface.

grpc-checks

An example service that exposes a gRPC healthcheck endpoint

generate protobuf

Note that main.go also includes this as a go:generate directive so that running this by hand is not necessary

$ protoc -I ./health ./health/health.proto --go_out=plugins=grpc:health

build & run example

Generate, compile, and run the example server.

go generate
go build
go run main.go

publish

Testing locally

$ docker build -t hashicorpnomad/grpc-checks:test .
$ docker run --rm hashicorpnomad/grpc-checks:test
