[PATCH 03/15] scripts/qmp: redirect qom-xxx scripts to python/qemu/qmp/

[John Snow <jsnow@redhat.com>]

Redirect to the new qom scripts. These forwarders can be deleted
eventually when there has been more time for the dust on the Python
packaging to settle and people understand how to find these commands.

Note: You can run these by setting $PYTHONPATH in your shell and then
running "python3 -m qemu.qmp.qom", or you can install the qemu namespace
package and use the "qom" or "qom-set" scripts.

I've written how to install the package elsewhere, but for the sake of
git-blame, cd to ./python, and then do:

- pip3 install [--user] [-e] .

--user will install to your local user install (will not work inside of
  a venv), omitting this flag installs to your system-wide packages
  (outside of a venv) or to your current virtual environment (inside the
  venv).

  When installing to a venv or to your system-wide packages, "qom"
  should be in your $PATH already. If you do a user install, you may
  need to add ~/.local/bin to your $PATH if you haven't already.

-e installs in editable mode: the installed package is effectively just
 a symlink to this folder; so changes to your git working tree are
 reflected in the installed package.

Alternatively to the above, If you have `pipenv` installed (`pip3
install --user pipenv`), you may also invoke 'pipenv shell' to enter a
pipenv-managed virtual environment (as a shell process that you may
leave with ctrt+d) that has 'qom' already in $PATH.
