Allow bson objects as job inputs, e.g. datetime.datetimes

[mcgalcode]

Summary

Adds the allow_bson=True kwarg to the jsanitize invocation in contains_job_or_flow utility function, and a corresponding test case. I recently tried to pass an object containing a datetime.datetime in it as an input to a job (specifically, the object was an emmet TaskDoc. This object was the output of another job (and I had retrieved it from the jobstore).

I noticed that every other invocation of jsanitize in the codebase uses allow_bson=True, with the exception of the one in Job::as_dict, so I concluded that this might be a bug. Please feel free to close if this behavior is intentional! However, I think it's useful to allow things like datetimes as inputs (at least to allow the use of TaskDocs as input parameters).

Checklist

Work-in-progress pull requests are encouraged, but please put [WIP] in the pull request
title.

Before a pull request can be merged, the following items must be checked:

• Code is in the standard Python style.
  The easiest way to handle this is to run the following in the correct sequence on
  your local machine. Start with running black on your new code. This will
  automatically reformat your code to PEP8 conventions and removes most issues. Then run
  pycodestyle, followed by flake8.
• Docstrings have been added in theNumpy docstring format.
  Run pydocstyle on your code.
• Type annotations are highly encouraged. Run mypy to
  type check your code.
• Tests have been added for any new functionality or bug fixes.
• All linting and tests pass.

Note that the CI system will run all the above checks. But it will be much more
efficient if you already fix most errors prior to submitting the PR. It is highly
recommended that you use the pre-commit hook provided in the repository. Simply
cp pre-commit .git/hooks and a check will be run prior to allowing commits.
