epee: regularly cleanup connections we kept a reference to

Browse source 
Since connections from the ::connect method are now kept in
a deque to be able to cancel them on exit, this leaks both
memory and a file descriptor. Here, we clean those up after
30 seconds, to avoid this. 30 seconds is higher then the
5 second timeout used in the async code, so this should be
safe. However, this is an assumption which would break if
that async code was to start relying on longer timeouts.
