Add the ability to switch transport API (#435)

feat(transport): add the ability to switch transport API

For the browser version of PubNub SDK, add the ability to switch between `fetch` and `xhr` APIs
(`transport` configuration option).

fix(event-engine): handshake/receive requests timeout

Fix issue because of which, in Event Engine mode, wrong timeout values have been set for requests
which creates long-poll request.

refactor(request): make sure request cancels on timeout

Refactor `timeout` implementation for `fetch` transport to properly cancel request when the
timeout timer will fire.
