MPM shell now supports script execution. It utilizes the cmdqueue of
Pythons cmd.Cmd class for this. The script to execute is a text file
containing the commands one per line.
The output decoration of MPM shell changed. Commands are decorated with
">" whereas responses use "<" at line start. Multiline responses are
decorated in each line.
Cleanup overwritten methods of cmd.Cmd to allow proper shutdow in
interactive as well as in scripted mode.
Improved pylint score.
If we use threading, the claimer loop's thread won't get scheduled in a
timely manner on n3xx. Using multiprocessing frees the claimer loop from
using the same GIL and gives back timely reclaim calls.
On the RPC server side, we keep track of which methods require a claim
token. MPM shell uses this info to automatically add claim tokens when
required.
