Docker Machine v0.5.1 breaks compatibility with v0.5.0 drivers #2325
Description
This particularly affects use of drivers not distributed with the machine binary.
For simplicity this is demonstrated with the virtualbox driver.
Steps to reproduce
$ git clone https://github.com/docker/machine.git$ cd machine && git checkout v0.5.0$ go build -a -o /usr/local/bin/docker-machine-driver-virtualbox cmd/machine-driver-virtualbox.go$ git checkout v0.5.1$ go build -a -o /usr/local/bin/docker-machine cmd/machine.go$ docker-machine create -d virtualbox
Expected result
Machine continuous to work
Actual result
Error occurs and Machine exits
WARNING >>> Error attempting heartbeat call to plugin server: rpc: can't find service RPCServerDriver.Heartbeat
Error attempting to invoke binary for plugin 'virtualbox': rpc: can't find service RPCServerDriver.GetVersion
This is probably caused by commit 89d9854 which changed the RPC API interface breaking compatibility with all drivers compiled against v0.5.0 or earlier.
