BUG/MINOR: lua: don't expose internal proxies

Browse Source 
Since internal proxies are now in the global proxy list, they are now
reachable from core.proxies, core.backends, core.frontends.

This patch fixes the issue by checking the PR_CAP_INT flag before
exposing them in lua, so the user can't have access to them.

This patch must be backported in 2.5.
