nghttpx: Lookup backend host name dynamically
...
We have added "dns" parameter to backend option. If specified, name
lookup is done dynamically. If not, name lookup is done at start up,
or configuration reloading. nghttpx caches DNS result including error
case in 30 seconds in this commit. Later commit makes this
configurable.
DNS resolution is done asynchronously using c-ares library.

starts when request handling finished, and timer stops when request

nghttpx: Restructure mode settings
...
It is very hard to support multiple protocols in backend while
retaining multiple mode settings. Therefore, we dropped modes except
for default and HTTP/2 proxy mode. The other removed modes can be
emulated using combinations of options. Now the backend connection is
not encrypted by default. To enable encryption on backend connection,
use --backend-tls option.

nghttpx: Rewrite backend HTTP/2 connection coalesce strategy
...
Previously, we use one Http2Session object per DownstreamAddrGroup.
This is not flexible, and we have to provision how many HTTP/2
connection is required in advance. The new strategy is we add
Http2Session object on demand. We measure the number of attached
downstream connection object and server advertised concurrency limit.
As long as former is smaller than the latter, we attach new downstream
connection to it. Once the limit is reached, we create new
Http2Session object. If the number lowers the limit, we start to
share Http2Session object again.
