[Proposal] `dapr stop` should wait until process actually exits

[philliphoff]

Describe the proposal

Currently the dapr stop command executes a kill command (or equivalent, for Windows) to stop a dapr or daprd process. However, this is asynchronous; the process may still take some time to actually exit. Scripts or other tooling that use the dapr stop command may have an expectation that, upon completion of dapr stop, processes have actually exited.

dapr stop should ensure that the process has exited before the command itself exits (within a suitable or perhaps configurable timeout).

This issue has been automatically marked as stale because it has not had activity in the last 30 days. It will be closed in the next 7 days unless it is tagged (pinned, good first issue, help wanted or triaged/resolved) or other activity occurs. Thank you for your contributions.

I think adding a --wait,-w flag for stop with a default timeout will be good. Additionally, after the configured timeout, the process should be checked again to make sure it has exited.
