* Gossip large messages via SendReliable
For messages beyond half of the maximum gossip
packet size, send the message to all peer nodes
via TCP.
The choice of "larger than half the max gossip
size" is relatively arbitrary. From brief testing,
the overhead from memberlist on a packet seemed to
only use ~3 of the available 1400 bytes, and most
gossip messages seem to be <<500 bytes.
* Add tests for oversized/normal message gossiping
* Make oversize metric names consistent
* Remove errant printf in test
* Correctly increment WaitGroup
* Add comment for OversizedMessage func
* Add metric for oversized messages dropped
Code was added to drop oversized messages if the
buffered channel they are sent on is full. This
is a good thing to surface as a metric.
* Add counter for total oversized messages sent
* Change full queue log level to debug
Was previously a warning, which isn't necessary
now that there is a metric tracking it.
