Jmespath cleanup and followup

[colleenXu]

There's a pile of jmespath-related issues to follow-up on and potentially close/cleanup:

A. Use filter, replace list_filter -> jmespath. Chunlei et al have been asking about this (3/28), so they can then remove outdated functionality

Notes

• Start w/ BioThings API queries -> try adjusting them
• note when yaml comments are old, but don't need to do all the work to update them
• Using filter, can we access the operations w/o action_type? See the yaml comment on MISSING

B. For all jmespath in MyChem, use modified always_list parameter. See if it fixes buggy behavior (BioThings issue 323). MyChem was updated with this support May 9 (Translator Slack link).

• Also implement: there's a use case for MyGene (summary here). Look for other cases where this is needed?

C. Try diff syntax (my thoughts) for these cases (MyChem, MyVariant) - trying to get publication info in reverse direction. Remember the parts of the response I want to keep (BioThings issue 324, 325)

D. drugcentral.bioactivity.action_type review

Notes: can assign BioThings issue to me to review, initial test to see if BioThings feature is working, then close BioThings issue. Then track actually implementing/using this feature in another issue like this one.
