Add the ability to set the cache mode when intercepting requests

[jgraham]

#721 adds a command to override the cache mode for all requests in a specific browsing context. But it could also be useful to override it for specific requests that are intercepted in the beforeRequestSent phase.

@jgraham I think that we can close this issue as dupe of #582?

[jgraham]

This is the issue you suggested I file for followup work related specifically to overrides in beforeRequestSent :)

Sorry, I misread. Should we actually discuss that next week?

@OrKoN, does Puppeteer currently use a per-interception-based network cache behavior? If not, is this something you might consider implementing?

[OrKoN]

Puppeteer does not use this currently and we do not have a feature request for it.
