[PATCH v2 01/11] python: rename QEMUMonitorProtocol.cmd() to cmd_raw()

[Vladimir Sementsov-Ogievskiy]

Having cmd() and command() methods in one class doesn't look good.
Rename cmd() to cmd_raw(), to show its meaning better.

We also want to rename command() to cmd() in future, so this commit is a
necessary first step.

Keep new cmd_raw() only in a few places where it's really needed and
move to command() where possible.
