Linux GEDS servers crash on a gateway registrations. The issue has been pushed back but still persist (specifically in Poll::add due to sock existing in the epoll context for some reason)

Cause of the crash analysis:
In order to post-construct the registered gateway, the unregistered gateway was moved within the newly allocated Gateway object. This move occurred before any form of network poll updating. This caused the network poll to incorrectly read an uninitialized portion of memory to find and remove or add a socket. To fix this, the socket is independently stored with the thread dependent on it.
