Summary:
This diff enables network inspection for WebSocket APIs, so by now XMLHttpRequest, Fetch and WebSocket are all supported. Android and iOS are both supported.
This diff monkey-patches the RCTWebSocketModule which WebSocket API builds on, and now it is able to intercept all WebSocket requests when app is running. The intercepted information of a WebSocket includes url, protocols, status, messages (sent and received), close reason, server close event and server error information, etc.

Summary: In previous `XHRInterceptor`, it sometimes crashes when restarting the network inspector because the id of the XHR objects are not unique all time. Fix this in diff by adding a global id "generator" for all intercepted xhr objects in order to make it safe across inspector restarts.

Summary: It sometimes happens that there are already some existing `XMLHttpRequest` objects before we turn on the network inspector. So it is a must to check whether a `XMLHttpRequest` object has a property `_index` to determine if it should be tracked.

Summary:
This diff adds a detail view for the network inspector. When pressing one item in the network flow list, a popup scrollView with detailed information about the network request will be shown. More interesting, the detail information is shown in real time, which means the detail information will be updated dynamically as soon as the network request is updated (maybe receiving a response after waiting).
Also have made sure this works on both Android and iOS.

Summary:
This diff adds a UI to display network information flows in the inspector tool (Android and iOS both supported):
- uses a ListView to show network flows, always scrolling to the latest item when a new network request occurs.
- displays the network requests as soon as they were created.
- highlights the selection row and toggles events to log the detailed intercepted information. (Next diff will draw UIs for this).
Follow-up:
- Will add one detail view to show all valuable information about a network request, after user clicks on one item in the ListView.
- Add more tabs in the detail view, ideally looking like the chrome network panel.

Summary:
This diff
- creates `XHRInterceptor` to intercept all XMLHttpRequest network operations in React Native by monkey-patching.
- enables `XHRInterceptor` in RN development tool "inspector".
This interception and inspector tool work well on both Android and iOS. And this supports interception on any network API based on XMLHttpRequest, especially the Fetch API.
By now, we can intercept 12 information fields of a XMLHttpRequest including method, url, data sent, status, response type, response size, requestHeaders, responseHeaders, response, responseURL, responseType and timeout.
Follow-up:
- Will add UIs in the inspector on top of this diff, to display all the network operation information. (Not in this diff just to make this shorter)
- Will extend this to gather other valuable information towards one XMLHttpRequest.
- Should support other network request APIs like WebSocket.
