Remove and mock doc dependencies because readthedocs is OOM

[snisarg]

ReadTheDocs has limited memory to import docs. We can mock some of the modules that we are not really using for documentation purposes so as the keep the process light-weight and not OOM ReadTheDocs, keeping room for future modules as well.

Note that this still fails because of a new, untest error introduced. Trying to keep 1 diff to do one thing only, the fix for the error right now will be on top of this diff.
