botframework-connector contains Node-only Dependencies

[justinwilaby]

The dependency request is a very heavy node-only dependency that prevents this package from being used in a web client. It can be easily replaced by node-fetch or some other fetch-like polyfill for the 2 calls that is it used for and would eliminate a great number of dependencies from the package.

Justin and I talked this afternoon. The key takeaways is that request makes the package Node specific, that request is only used in one http request and that request is a very heavy dependency. There may be other Node specific dependencies inside of the library, but request could be swapped out for a more lightweight way of conducting http requests in a pollyfilled manner, which would allow the library to be used in the browser.
