LUA Record Type for Lua-powered DNS records for standards based fail-over and geographical load balancing

GitHub branch -> https://github.com/ahupowerdns/pdns/tree/luarec

Recently, many zone owners could not migrate away from Dyn since they were benefiting from non-standardised DNS-based failover and geographical loadbalancing features. What you see below is an attempt to get standards based but flexible equivalents of these currently proprietary features. Here is a zone:

$TTL 60
lua.br. IN      SOA     a.lua.br. nstld.verisign-grs.com. (
        2016032300      ; Serial
        14400           ; Refresh

	-- apache's %r log field (request line) is read only, we can't fix data in there,
	-- so you need to change your LogFormat with '%m %U%q %H' instead of '%r' to get this masking effect
	function log_mask_password(r)
	-- manually parse request line, needed to overwrite r.uri to mimick apache's %r percent-encoding in %U for non-latin chars
	local url = r.the_request:match"^%S+%s(.+)%sHTTP/[%d.]+$" -- ex.: GET /foo?bar=1 HTTP/1.1

	-- in case of malformed http request, use apache's uri variant
	if not url then
	url = r.uri
	end

	This script will echo each line in either stdin or a given file,
	with a 1/50th of a second delay between each. This makes it
	suitable for "playing" the animations found on textfiles.com:

	Just use it like this:

	require "string"

	entry point.

	r.content_type = "text/plain"
