Add podman backend

[mfulz]

closes #85

This is a first working podman backend, which can be used by calling the agent with --use-podman.

It is working on my environment fine for now, but would need broader testing.

This is a early version and cannot be called stable at all for now, but it makes sense to include it eary in my opinion.

It will take me some time but I'll do migrate them one by one ... - you can just merge master into from time to time to check if it will start working untill it do ;)

Great I'lll work further on the implementation in between as well

@mfulz now it is building - I think you can move forward :)

Is this in essence compatible with next or would it need a complete rewrite? (assuming it was based off from 0.15.x initially).

It targets the main branch ... so its next what ever version next is going to be when it's finished :)

The interface for backends did not changed that mouch ... at all anyway

@mfulz Are you still using your interface or WP at all? Curious how close this is to be "production ready", also given how long this PR is already open :)

Sorry for the silence atm this is stalled for me, as I'm loaded with too much other things, that cannot be postponed :(
I was just checking wp out and drafted the podman stuff and definitely go to proceed with this.

But when this will happen is impossible to tell atm. could be end of this year or next year - sorry for that

EDIT: Sorry the mark ready was a missclick

[mfulz]

At least I can fix the errors for the checks if that would help.
But I cant access the details on what is failing for the test, can someone help me out here?

Well then just let it open as is ... open pulls per se dont hurt.

Others can base new pulls on it or this gets ready ...
