We actually produce an invalid JSON error at the moment: bitcoin-cli
complains "JSON value is not an integer as expected" rather than returning
the given error. Make our error a valid JSON RPC error.

Got a spurious failure in test_no_fee_estimate; we fired too soon from the logs (presumably
we raced in on the first response, but estimatesmartfee gets called 3 times).

This is a simple reverse proxy that `bitcoin-cli` can talk to when invoked by
`lightningd`. It allows us to trace `bitcoin-cli` calls, and intercept calls to
mock the replies, better than the current bash-script based method.
