Migrate to modules, refactor Makefile and use Travis for CI
- migrate to Go modules and remove vendor - refactor Makefile - add version package and store version - split extras from the rest - use travis for CI Change-Id: I81b35220653b0f7c9a0fcdd4c527d691ec1e96c1 Signed-off-by: Ondrej Fabry <ofabry@cisco.com>
