Support passing android serial as parameter - improvement for dumpapp script about stetho

[jasta]

We wanted to avoid this in dumpapp because currently most of the option parsing happens on the server itself (-p is the only option parsed by the client). That said, we could add more by making the parser a little more sophisticated (remember, we have to actually remove the options parsed locally before they're sent to the Stetho server).

I'd be happy to accept a diff which adds -s / --serial but do note that ANDROID_SERIAL=foo ./scripts/dumpapp -p ... blabla would function the same without the same side effects in the shell that export causes. This is how we internally use dumpapp for automation.

Maybe the issue is just that ANDROID_SERIAL isn't documented.

Thanks for your insight. I have not realized that ANDROID_SERIAL=foo would be sufficient in automation. That would be sufficient for me.

@jasta Is it possible to specify a device with ./dumpapp -s? I have multiple devices attached at my testlab, and would love to use Stetho on any particular one of them.

@jasta @jhuska : Is this fixed as part of latest code?
