Review comment:
       i agree with you . if people installed apisix by `make install` , it 
will be ok.
   
   but if people installed it by apisix rpm-package , apisix.lua will in ` 
/usr/local/apisix/apisix/cli/ `
   
   Should we integrate these two paths? After all, bash can't easily find 
multiple paths like Lua.

Review comment:
       if we always use `luajit` of openresty , it will be a big chage for old 
users . so we think maybe we should leave a way for old users ?
