commands/commands: Get tests to pass

* commands/commands.go

- Use package
`github.com/lambda-linux/lambda-machine-local/commands/mcndirs` instead
of `github.com/docker/machine/commands/mcndirs`

- `var Commands = []cli.Command{}` and `commands := map[string](func()
error){}` are empty. This will be populated in subsequent commits when we
import commands

* commands/commands_test.go

- Removed tests
  + TestRunActionForeachMachine
  + TestPrintIPEmptyGivenLocalEngine
  + TestPrintIPPrintsGivenRemoteEngine

We will add them back in subsequent commits

- Add environment variable `BUGSNAG_ENABLE` so we can control invocation of
bugsnag when running tests

Tests can be run using,

```
$ go test -v -race -tags "" github.com/lambda-linux/lambda-machine-local/commands -run "Test*"


$ BUGSNAG_ENABLE=1 go test -v -race -tags "" github.com/lambda-linux/lambda-machine-local/commands -run "Test*"
```
