Add keepalive_tolerance http2 option
The number of unacknowledged pings that can be tolerated
before the connection is forcefully closed.
When a keepalive ping is sent to the peer, a counter is
incremented and if this counter exceeds the tolerance limit,
the connection is forcefully closed. The counter is
decremented whenever a ping ack is received from the peer.
By default, the mechanism for closing the connection based
on ping and ping ack is disabled.
Loïc Hoguin: I have edited a lot of the code and renamed
a few things as well as simplified the docs and increased
test timeouts to avoid race conditions.
