Podman machine resets all providers

Browse Source 
Podman machine reset now removes and resets machines from all providers availabe on the platform.

On windows, if the user is does not have admin privs, machine will only reset WSL, but will emit a warning that it is unable to remove hyperV machines without elevated privs.
