MINOR: hlua: Add support for the "http-after-res" action
This commit introduces support for the "http-after-res" action in hlua, enabling the invocation of a Lua function in a "http-after-response" rule. With this enhancement, a Lua action can be registered using the "http-after-res" action type: core.register_action('myaction', {'http-after-res'}, myaction) A new "lua.myaction" is created and can be invoked in a "http-after-response" rule: http-after-response lua.myaction This addition provides greater flexibility and extensibility in handling post-response actions using Lua. This commit depends on: - 4457783 ("MINOR: http_ana: position the FINAL flag for http_after_res execution") Signed-off-by: Sébastien Gross <sgross@haproxy.com>
