Offer the ability to disable Pretty Printed JSON over the wire

[pickypg]

Currently, NEST will pretty print the HTTP. For those concerned with reducing network traffic, the best option is to use EnableHttpCompression(), which exists today on ConnectionSettings.

It would be nice to also add the ability to disable pretty printing at the same level, either as an opt-in option (EnablePrettyPrint(), thereby changing the current behavior) or as an opt-out feature (DisablePrettyPrint(), thereby maintaining the same behavior).

Actually I'm the one who is interested in this feature. Overhead is pretty big for complex queries.
