This patch makes RiotX use an unbounded thread pool to handle
connections. The default thread pool for the android WorkManager has a
fairly anemic number of threads and I suspect this was causing
performance issues especially because of all the long-running jobs that
happen whenever you sync.
I tested this out on my phone and all of the sluggishness appears to
have gone away. I tested both the debug and release builds to make sure
it wasn't just some release optimization. RiotX is so much snappier now!
This fixes#1221
