Subject: Started deferring leap session creation #759

Started adapting get_leap_session to deferreds

Soledad and keymanager setup calls will now
happen in deferreds and leap session creation
itself is a deferred with callbacks

This is a start in breaking the big blocking
calls we were doing on the main thread, this
was done without changing code inside the
leap libraries yet so things can be further
optimized

This breaks the ~4 seconds get_leap_session
piece into smaller 1 seconds one, that can be
further optimized and deferred to even smaller
calls

There are requests calls happening on the main
thread that should get this number even further
down

Also moved some pieces from bitmask libraries
to our bootstrap, because they are not bitmask
libraries anymore and that was causing confusion
