Tye cannot shutdown with executable service

[philliphoff]

When an "executable" service is part of the application, Tye can't shutdown. This occurs at least within a VS Code Dev Container, with a Node.js based service, but perhaps occurs elsewhere. This happens both when using Ctrl+C from the terminal as well as when using Tye's shutdown command on its control plane. Tye shuts down everything else, but seems to be stuck waiting for that service to stop.

Debugging notes: this seems to be a hang at a Process.WaitForExit() call when shutting down processes. In particular, I see this with dapr.exe processes, but only on Windows and Linux, but not Mac. (I've seen some issues when browsing the .NET runtime repos that seem related, where processes that themselves run long-running processes that redirect output (such as dapr.exe which runs daprd.exe) can sometimes not read to the EOF, which causes the wait to be indefinite.).

Since these are expected to be long running processes and we're typically not concerned with capturing all of its output--that is, it's probably ok for some output to be lost on shutdown, since Tye is shutting down anyway, we might instead just call Process.WaitForProcessExit(timeout) for some suitable timeout as an immediate fix.
