HTTP/2 support
HTTP/2 gives a number of optimizations, while keeping support for the protocol. HTTP/2 support was recently added to the Redfish specification. The largest performance increase in bmc usage is likely header compression. Almost all requests reuse the same header values, so the hpack based compression scheme in HTTP/2 allows OpenBMC to be more efficient as a transport, and has the potential to significantly reduce the number of bytes we're sending on the wire.
This commit adds HTTP2 support to bmcweb through nghttp2 library. When static linked into bmcweb, this support adds 53.4KB to the bmcweb binary size. nghttp2 is available in meta-oe already.
Given the experimental nature of this option, it is added under the meson option "experimental-http2" and disabled by default. The hope is to enable it at some point in the future.
To accomplish the above, there a new class, HTTP2Connection is created. This is intended to isolate HTTP/2 connections code from HttpConnection such that it is far less likely to cause bugs, although it does duplicate about 20 lines of code (async_read_some, async_write_some, buffers, etc). This seems worth it for the moment.
In a similar way to Websockets, when an HTTP/2 connection is detected through ALPN, the HTTP2Connection class will be instantiated, and the socket object passed to it, thus allowing the Connection class to be destroyed, and the HTTP2Connection to take over for the user.
Tested: Redfish service validator passes with option enabled With option disabled GET /redfish/v1 in curl shows ALPN non negotiation, and fallback to http1.1
With the option enable GET /redfish/v1 in curl shows ALPN negotiates to HTTP2
