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.

Note: installing these packages to an environment outside a venv can be
dangerous: Many QEMU scripts will begin to prefer the installed version
instead of the version directly in the tree. Use with caution. editable
mode is recommended when working outside of a venv.
