🐛 `-o` / `--container_option` does not work as expected

[shnizzedy]

Describe the bug

The option is listed in the README as

  -o [OPT [OPT ...]], --container_option [OPT [OPT ...]]
                        parameters and flags to pass through to Docker or Singularity

                        This flag can take multiple arguments so cannot be
                        the final argument before the command argument (i.e.,
                        run or any other command that does not start with - or --)

defined here https://github.com/FCP-INDI/cpac/blob/46af66edfaf8547a5eb79016d9cdd8c3e25ae13a/src/cpac/__main__.py#L74-L83

but I don't see that parameter handled anywhere

Passing options through don't seem to work with any syntax I've attempted (see "To reproduce" below).

To reproduce

cpac -o --entrypoint=/bin/bash --platform docker run

cpac: error: argument -o/--container_option: expected one argument

cpac -o "--entrypoint=/bin/bash" --platform docker run

cpac: error: argument -o/--container_option: expected one argument

cpac -o="--entrypoint=/bin/bash" --platform docker run

cpac run: error: the following arguments are required: bids_dir, output_dir, level_of_analysis, extra_args

cpac -o="--entrypoint=/bin/bash" --platform docker run bids_dir outputs_dir participant

run.py: error: unrecognized arguments: -o=--entrypoint=/bin/bash

Expected behavior

Any options passed to -o or --container_option are passed through to Docker or Singularity.

Acceptance criteria

• [ ] cpac -o="--entrypoint=/bin/bash" --platform docker run opens a BASH prompt in a C-PAC Docker container
