contrib.cp: Adding SequenceVar and other logical expressions for scheduling

Code for infeasibility diagnostics called mis (Pyomo#3172)

* getting started moving mis code into Pyomo contrib

* we have a test for mis, but it needs more coverage

* now testing some exceptions

* slight change to doc

* black

* fixing _get_constraint test

* removing some spelling errors

* more spelling errors removed

* update typos.toml for mis

* I forgot to push the __init__.py file in tests

* a little documentation cleanup

* moved mis to be part of iis

* correct bad import in mis test

* I didn't realize it would run every py file in the test directory

* trying to get the Windows tests to pass by explicitly releasing the logger file handle

* run black on test_mis.py

* trying to manage the temp dir using the tempfilemanager as a context

* catch the error that kills windows tests

* run black again

* windows started passing, but linux failing; one quick check to see if logging.info helps:

* run black again

* On windows we are just going to have to leave a log file from the test

* add a test for a feasible model

* Update pyomo/contrib/iis/mis.py
