rename working_dir to workdir for consistency

Currently `podman-py` uses all three versions of `work_dir`,
`working_dir` and `workdir` (not to mention `WorkingDir`).

This commit tries to unify the parameter usage by allowing `workdir` for
container `create` or `run`. For backwards compatibility `working_dir`
still works but a deprecation warning is added.

Since upstream Podman uses a variety of *workdir* versions the
`podman-py` codebase can't be simplified further.

Fix: #330
