Introduce gRPC API proof of concept
This commit introduces a new `grpc` module including the following key
types:

 - BisqGrpcServer: The API implementation itself, along with generated
   gRPC Response/Reploy types defined in grpc/src/main/proto/grpc.proto.

 - BisqGrpcServerMain: A 'headless' / daemon-like entry point for
   running a Bisq node without the JavaFX desktop UI.

 - BisqGrpcClient: A simple, repl-style client for the API that allows
   the user to exercise the various endpoints as seen in the example
   below.

In the `desktop` module, the BisqAppMain class has been modified to
start a BisqGrpcServer instance if the `--desktopWithGrpcApi` option has
been set to `true`.

In the `core` module, a new `CoreApi` class has been introduced
providing a kind of comprehensive facade for all Bisq functionality to
be exposed via the RPC API.

How to explore the proof of concept:

 1. Run the main() method in BisqAppMain providing
 `--desktopWithGrpcApi=true` as a program argument or alternatively, run
 the main() method in BisqGrpcServerMain, where no special option is
 required. In either case, you'll notice the following entry in the log
 output:

    INFO  bisq.grpc.BisqGrpcServer: Server started, listening on 8888

 2. Now run the main() method in BisqGrpcClient. Once it has started up
 you are connected to the gRPC server started in step 1 above. To
 exercise the API, type `getVersion` via stdin and hit return. You
 should see the following response:

    INFO bisq.grpc.BisqGrpcClient - 1.2.4

 Likewise, you can type `getBalance` and you'll see the following
 response:

    INFO bisq.grpc.BisqGrpcClient - 0.00 BTC

 and so forth for each of the implemented endpoints. For a list of
 implemented endpoints, see BisqGrpcServer.start().

Note once again that the code here is merely a proof of concept and
should not be considered complete or production-ready in any way. In a
subsequent commit, the `--desktopWithGrpcApi` option will be disabled in
order to avoid any potential production use.

The content of this commit is the result of squashing a number of
commits originally authored by chimp1984 in the `chimp1984` fork's `grpc`
branch.
