Subject: image_create: partial integration into python

Integrates some parts of this operation into native code, eg: the md5
checksum computation.

Wraps non native processes and commands using the subprocess module.
For example, legacy.py stores bash commands pending integration.

Supports python >=3.6, expected until more modern ogLives are put into
production environments.
