HTTP/2: removed http2_idle_timeout and http2_max_requests.

Instead, keepalive_timeout and keepalive_requests are now used.  This
is expected to simplify HTTP/2 code and usage.  This also matches
directives used by upstream module for all protocols.

In case of default settings, this effectively changes maximum number
of requests per connection from 1000 to 100.  This looks acceptable,
especially given that HTTP/2 code now properly supports lingering close.

Further, this changes default keepalive timeout in HTTP/2 from 300 seconds
to 75 seconds.  This also looks acceptable, and larger than PING interval
used by Firefox (network.http.spdy.ping-threshold defaults to 58s),
the only browser to use PINGs.
