[issue5585] implement initializer for multiprocessing.BaseManager.start()

[lekma]

New submission from lekma <lekmalek at gmail.com>:

It would be useful to have the ability to run arbitrary code before a
manager's server subprocess is started (I'd use this feature to install
signal handlers for example).
