Use grpc 1.6.0 and update all the things
- Update go-grpc to 1.6.0. Includes license change from BSD 3-clause to Apache 2
- Update grpc-ecosystem/go-grpc-middleware to latest (needed for go-grpc 1.6.0 compatibility)
- Switch from github.com/Sirupsen/logrus to github.com/sirupsen/logrus (needed for latest go-grpc-middleware)
- Add golang.org/x/crypto, a dependency of latest logrus
