[shellprocess] Stub of a shell process module.

This is basically dummyprocess, except with an expanded configuration
interface so you can run 1 or more shell commands in the live
or target system with a suitable configuration file and instance
of shellprocess in settings.conf.

It can replace downstream modules that implement their own
process modules with a command, by an instance of shellprocess.
