The majority of relative imports in the nvp plugin will be fixed in blueprint nvp-api-client-loadbalance-request. This patch removes the rest of them in and moves the vim tabstop line to the top of the header file to be consistent with the rest of the files in quantum. Fixes bug 1091596 Change-Id: I6c8299ca73ae5df75c87f302680908f863f81f02
