Thank you for submitting a PR @rikatz.

The current set of Lua directives supported by crossplane focus on supporting ngx_http_lua_module. I think the changes you're making are releated to ngx_stream_lua_module.

@xynicole @dengsh12 Should we support this module by merging the flags into moduleLuaDirectives or do we want to model it as a separate optional module?

@ornj I am leaning towards the second option as it provides better modularity and clarity. Additionally, since it involves two separate repositories, it would be easier to use a generate approach rather than manually adding the directives. Furthermore, since the ngx_stream_lua_module is not distributed with NGINX by default, using it as a separate optional module allows us to avoid affecting the existing ngx_http_lua_module directives.

I thought in a separate file is easier for management and make more sense. It seems they are registered as two modules in fact(different ngx_module_t). If we merge into one file it comes to a new special case(and seems a bit weird) for the code generator. The relationships among ParseOptions.DirectiveSources is or so put them in two files won't hurt any valid config files.

After the go generate tool available it should be easy to add & keep update for it. Since we have specialize bitmasks for block directives in http_lua_module, I wonder if we also need some special operations for this module?
