Add /crawl cgi request feature to peer protocol (RIPD-729):

Browse Source 
This adds support for a cgi /crawl request, issued over HTTPS to the configured
peer protocol port. The response to the request is a JSON object containing
the node public key, type, and IP address of each directly connected neighbor.
The IP address is suppressed unless the neighbor has requested its address
to be revealed by adding "Crawl: public" to its HTTP headers. This field is
currently set by the peer_private option in the rippled.cfg file.
