Subject: [PATCH] Merge #14777: tests: Add regtest for JSON-RPC batch calls

3d2c7d6f94 Add regtest for JSON-RPC batch calls. (Daniel Kraft)

Pull request description:

  This adds a new regtest file `interface_rpc.py`, containing a test for batch JSON-RPC requests.  Those were previously not tested at all.  Tests for basic requests are not really necessary, as those are used anyway in lots of other regtests.

  The existing `interface_http.py` file is more about the underlying HTTP connection, so adding a new interface file for the JSON-RPC specific things makes sense.
