this is the only return type change, being more consistent felt like it belonged here even if we don't use cancel yet

extracting session and networkMonitor to parameters are the only substantive changes in this PR

directly using executionContext is an FR-compat change and functionally equivalent to using driver when isolation is disabled

Summary
Paves the way for adding the extra waitFor methods needed for #11180 in a way that still helps out with fraggle rock and makes future testing easier.
This is a move and slight restructuring to convert
thisreferences to parameters only. No functionality changes, and no substantive test additions (though the gaps are much more obvious and should be much easier to test now).Related Issues/PRs
