Setting to retain ansible inventory for all buffers created

[ari-II]

It's useful to have the option to retain all ansible playbooks created for later debugging/review. Currently the method captures it along with the .venv and binaries which can fill the filesystem.
Using ansible tempdir: /tmp/fsPlQCMRnH_830051621

Perhaps call it DAC_RETAIN_INVENTORY

We did used to have something like that, but /tmp filled up quite quickly with no one preuning it. Which is why I went for the CLI command to regenerate a directory if required.

But this seems like a good idea.
