chore: Enable Podman as a Docker alternative

[jeremyary]

Is your feature request related to a problem? Please describe.
Feast is currently using Docker for local-container & CI integration test runs backed by various code-checks regarding test containers. Docker has recently updated licensing for Docker desktop making installations for large enterprise team members troublesome. Aside from local runs, throttling was added for anonymous users on public repositories as well. This is not something that's become an issue for Feast just yet, but we have encountered it with other growing projects, esp. around CI.

Describe the solution you'd like
We'd like to see Podman support enabled in a non-invasive way. The Podman community has done a lot of work to ensure that drop-in replacement is as seamless as they can manage, so there are tools available for local aliasing, etc. to aid in implementation.
