Fixed flaky TestBackgroundCombinedOutputFailure (#978)
## Changes
`TestBackgroundCombinedOutputFailure` was occasionally failing because
combined output could have been in different order, see

Added process stubbing for easier testing of launched subprocesses (#963)
## Changes

This PR makes unit testing with subprocesses fast.

```
	ctx := context.Background()
	ctx, stub := process.WithStub(ctx)
	stub.WithDefaultOutput("meeee")

	ctx = env.Set(ctx, "FOO", "bar")

	out, err := process.Background(ctx, []string{"/usr/local/bin/meeecho", "1", "--foo", "bar"})
	require.NoError(t, err)
	require.Equal(t, "meeee", out)
	require.Equal(t, 1, stub.Len())
	require.Equal(t, []string{"meeecho 1 --foo bar"}, stub.Commands())

	allEnv := stub.CombinedEnvironment()
	require.Equal(t, "bar", allEnv["FOO"])
	require.Equal(t, "bar", stub.LookupEnv("FOO"))
```

This should make further iterations of
https://github.com/databricks/cli/pull/914 easier

Added `process.Background()` and `process.Forwarded()` (#804)
## Changes
This PR adds higher-level wrappers for calling subprocesses. One of the
steps to get https://github.com/databricks/cli/pull/637 in, as
previously discussed.

The reason to add `process.Forwarded()` is to proxy Python's `input()`
calls from a child process seamlessly. Another use-case is plugging in
`less` as a pager for the list results.
