Salvatore Orlando 95809f59c5 Remove nvplib and move utility methods into nsxlib
This patch completes the process of moving code from nvplib
to nsxlib. Utility methods such as do_request and get_all_query_pages
are transferred into nsxlib, so that nvplib can be safely removed.

Partially implements blueprint nicira-plugin-renaming
