HTTP/2: removed server push (ticket #2432).
Although it has better implementation status than HTTP/3 server push,
it remains of limited use, with adoption numbers seen as negligible.
Per IETF 102 materials, server push was used only in 0.04% of sessions.
It was considered to be "difficult to use effectively" in RFC 9113.
Its use is further limited by badly matching to fetch/cache/connection
models in browsers, see related discussions linked from [1].
Server push was disabled in Chrome 106 [2].
The http2_push, http2_push_preload, and http2_max_concurrent_pushes
directives are made obsolete. In particular, this essentially reverts
7201:641306096f5b and 7207:3d2b0b02bd3d.
