initial convertion of provision.sh and helpers to python as per https…

[stratus-ss]

What does this PR do?

Converts the shell to python. No new functionality has been added.

How should this be manually tested?

Usage is almost the same as the shell. Argparse in this case is not looking for -argument= but rather just -argument.

usage: provision.py [-h] [--inventory INVENTORY_FILE]
                    [--installer-path INSTALLER_PATH]
                    [--extra-vars EXTRA_VARS [EXTRA_VARS ...]]

 ./provision.py -i /path/to/hostfile -p /path/to/installer

Is there a relevant Issue open for this?

@stratus-ss tested this out, looks like there are some dependencies missing:

I updated the PR comments to reflect the fact that it functions almost like the shell, but argparse is not looking for the '=' sign. If requested this can be added in

@stratus-ss no, spaces are fine, but even when I do that, it still bombs at the same place:

[root@f767439a12f0 ~]# ./repository/rhc-ose-etsauer/rhc-ose-ansible/provision.py -i ./repository/rhc-ose-env-configs/inventory/provision-openstack.casl.pr -p ./repository/openshift-ansible/ -e 'openstack_key_name=esauer-util3'

[stratus-ss]

This should be fixed... I had combine the .communicate() and the return code on one line which was causing subprocess to throw a No such file or directory error for some reason.

In my small environment it works, will need to test in an actual environment

@stratus-ss now when I run it, it hangs with no output...
