glusterd: Fix management encryption issues with GlusterDv3.6.4
Backport of commit 01b82c6 from master Management encryption was enabled incorrectly in GlusterD leading to issues of cluster deadlocks. This has been fixed with this commit. The fix is in two parts, 1. Correctly enable encrytion for the TCP listener in GlusterD and re-enable own-threads for encrypted connections. Without this, GlusterD could try to esatblish the blocking SSL connects in the epoll thread, for eg. when handling friend updates, which could lead to cluster deadlocks. 2. Explicitly enable encryption for outgoing peer connections. Without enabling encryption explicitly for outgoing connections was causing SSL socket events to be handled in the epoll thread. Some events, like disconnects during peer detach, could lead to connection attempts to happen in the epoll thread, leading to deadlocks again.
