Use ledgetech/lua-resty-http?

[plantfansam]

I see the project is using api7-lua-resty-http. That project is a fork of https://github.com/ledgetech/lua-resty-http, which seems better maintained.

Is there a reason the project is using the api7 fork? If not, would the maintainers accept a PR moving to use the original ledgetech rock?
