MINOR: server: add a max-reuse parameter

Some servers may wish to limit the total number of requests they execute
over a connection because some of their components might leak resources.
In HTTP/1 it was easy, they just had to emit a "connection: close" header
field with the last response. In HTTP/2, it's less easy because the info
is not always shared with the component dealing with the H2 protocol and
it could be harder to advertise a GOAWAY with a stream limit.

This patch provides a solution to this by adding a new "max-reuse" parameter
to the server keyword. This parameter indicates how many times an idle
connection may be reused for new requests. The information is made available
and the underlying muxes will be able to use it at will.

This patch should be backported to 1.9.
