Add rate-limited-ldp-communication package

@svrstich requesting for a review of the code and a possible merge with the main. I changed the basic LDPCommunication module to the RateLimited one I made a package for here and added it in the implementation.

Added an extra config to add the number of observations per LDP resource to be able to combat the socket hangups and reducing the number of GET requests done to fetch the stored sensor observations.
