[tinyipa] allow skipping python compileall

Browse Source 
Somtimes it is useful to have tinyipa image with normal Python
experience (access to source code for debugging, Python interpreter).

This patch allows to skip compiling all Python to *.pyo and
removing all *.py[c] files by setting

export PYOPTIMIZE_TINYIPA=false

in the shell before running the build scripts.

----------------
(De)Optimizing the image
~~~~~~~~~~~~~~~~~~~~~~~~
If you want the build script to preinstall everything into the ramdisk,
instead of loading some things at runtime (this results in a slightly bigger
ramdisk), before running make or build-tinyipa.sh run::
export BUILD_AND_INSTALL_TINYIPA=true
By default, building TinyIPA will compile most of the Python code to
optimized ``*.pyo`` files, completely remove most of ``*.py`` and ``*.pyc``
files, and run ironic-python-agent with ``PYTHONOPTIMIZE=1``
to save space on the ramdisk.
If instead you want a normal Python experience inside the image,
for example for debugging/hacking on IPA in a running ramdisk,
before running make or build-tinyipa.sh run::
export PYOPTIMIZE_TINYIPA=false
Enabling SSH access to the ramdisk
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you want to enable SSH access to the image, set ``ENABLE_SSH`` variable in
your shell before building the tinyipa::
