fix(install): restart stack containers that crash on first start (#25)

Browse Source 
Apps could fail install when a stack member exited on its first start
because a dependency (db/redis/the bitcoin node) was not ready yet — a
transient crash, not a broken install. wait_for_stack_containers now
restarts each exited/dead container up to 3 times before declaring the
install failed; the runtime supervisor keeps it alive afterwards.
