Add NDEx Pathways Integration

[inodb]

Adds NDEx pathways on pathways tab in the results view page. Related to cBioPortal/icebox#343.

Test URL: https://bit.ly/3vddazA

TODO:

• add iframe with iquery page that searches for queried genes rather than just an iframe of the homepage
• Do we want to combine pathwaymapper and NDEx as single tab, but using pills to navigate between them? So you would have one pill for pathwaymapper and one for NDEx inside of a pathways tab.
• Explain difference between NDEx and PathwayMapper in UI

We decieded not to include other alteration frequencies yet as part of this release:

• current alteration frequency does not reflect queries study and subset alteration frequency. We prolly need to pass that over. Sample IDs, plus study ids. Or we pass over a session id. Addressing later in: Endpoint to retrieve alteration frequencies icebox#383
  • decide interface (JSON format).
    "geneAnnotationServices": { "mutation": "https://iquery-cbio.dev.ucsd.edu/integratedsearch/v1/mutationfrequency", "alteration": "http://localhost/" }

Follow up with tests: cBioPortal/icebox#331

Let's use squash on merge button

@inodb should this really default to true?

[inodb]

thanks for checking - yeah i think it makes sense to have this be the default for all installations

FYI, you can now do urlResponse?.body?.webUrl?.startWith('...') and it will evaluate false if anything is undefined
