feat: Add volume to docker client and volume permission testing

[angela-ko]

Description of changes

• Add volume class to docker_client and docker_cleanup
• Add user flag to docker container run
• Add tests to explore folder permission issues: Testing had to be done with Volumes instead of bind mounts since MacOS's Docker runs Docker in a vm so bind mounts have to first be mounted into the vm and this leads to all sorts of weird uid mapping issues which would lead to inconsistent test results. The only way to consistently do this is via Volumes whose permissions are managed by Docker itself.
  • Tests explore volume with 700 mounted to another container with uid 1000 (simulating bind mounts kinda..? since the other container owns the directory we are mounting the volume to) read, write permissions
  • Explore ways to circumvent the permission issues (resolved in 2 different ways - having a root access container copy the file from the restricted folder to a folder with open permissions, and just calling chmod on the folder that's getting mounted before we swap to uid1000). These are also the two methods I had thought of that would work to achieve our goal of having a mount point that has no permission issues.
