Add an optional keyword 'shutdown_timeout' parameter to the
multiprocessing.BaseManager constructor.

Multiprocessing tests pass test.support.SHORT_TIMEOUT
to BaseManager.shutdown_timeout.

I don't think that having two separated timeout parameters, one for wait() and a second for join(), is needed. I prefer to have a single value. The process should be able to handle the shutdown command in 1.0 second, if it doesn't, terminate() should terminate it immediately and 1.0 should be enough to wait until the process is killed, no?

@pitrou: Would you mind reviewing the updated PR? I completed the doc and changed the behavior: kill the process if it is still alive shutdown_timeout seconds after being terminated.

gh-91231: Add shutdown_timeout to multiprocessing BaseManager

Add an optional keyword 'shutdown_timeout' parameter to the multiprocessing.BaseManager constructor. Kill the process if terminate() takes longer than the timeout. Multiprocessing tests pass test.support.SHORT_TIMEOUT to BaseManager.shutdown_timeout.
