Summary:
let's finally inspect flipper with flipper!
Here we have:
1) a self inspection client which implements FlipperClient interface from js sdk and FlipperClientConnection. It links back and front parts of self inspection
2) simple plugin (UI) to show messages
3) back part of that plugin - it sends all received messages to UI part via client
4) we initialize self inspection for dev builds only
P. S. filesystem dependency will be replaced with npm one before I ship it (need to publish to npm first)
