Add `mounts` argument to more `utils` components

[schmidt-ai]

Description

The python, copy, and maybe even the touch util components could benefit from having a mounts argument like the sh util does.

Motivation/Background

It's a slight convenience improvement to these utils because they might be used for dealing with e.g. mounted EFS volumes.

Detailed Proposal

Expand the signature of these util method definitions to include a mounts argument, and pass it into the corresponding Role constructor.

Alternatives

Wrap stuff in a call to utils.sh with your mounts.

Additional context/links

Happy to contribute!
