all: add configuration to limit max concurrent requests

Currently, there's no upper bound for how many requests that ctrld will
handle at a time. This could be problem on some low capacity routers,
where CPU/RAM is very limited.

This commit adds a configuration to limit how many requests that will be
handled concurrently. The default is 256, which should works well for
most routers (the default concurrent requests of dnsmasq is 150).
