Summary:
This shows progress for the download of the JS bundle (different from the packager transform progress that we show already). This is useful especially when loading the JS bundle from a remote source or when developing on device (on simulator + localhost it pretty much just downloads instantly). This will be nice for the expo client since all bundles are loaded over the network and can take several seconds to load.
This depends on https://github.com/facebook/metro-bundler/pull/28 to work but won't crash or anything without it, it just won't show the progress percentage.
**Test plan**
Tested that bundle download progress is shown properly in RNTester on both localhost + simulator and on real device with network conditionner to simulate a slow loading bundle.
Tested that it doesn't cause issues if the packager doesn't send the Content-Length header.

Summary:
In the Docs of `NSURLSession` ,
>IMPORTANT
>The session object keeps a strong reference to the delegate until your app exits or explicitly >invalidates the session. If you do not invalidate the session, your app leaks memory until it exits.
The RCTMultipartDataTask will cause memory leaks, it will make `RCTBatchedBridge` and ` RCTMultipartDataTask` will not release.
So call `[session finishTasksAndInvalidate];` at the end of `startTask` function.
