Support for additional privilege escalation options

[schewara]

I am currently playing around with pyinfra to see if it can replace my current config managment solution and hit one specific issue, where I want to configure permisions for rootless Podman containers.

Ansible for example, has the containers.podman.podman_unshare become plugin, which makes use of podman-unshare, but on first sight I did not find an easy way to get it done in pyinfra without jumping through some extra hoops.

Also seeing that there are even more available become plugins, I thought it would be great to have an easy way to use other escalation methods in pyinfra as well.
