Add various generator improvements

- generate service implementation for modules
- generate conversion maps and String() method for enums
- generate module name and version as constants
- rename Union_data field to XXX_UnionData for consistency
- generate constant GoVppAPIPackageIsVersionN for checking compatibility with API
- add example for using service clients
- add some documentation to socketclient adapter
- cleanup gen.go file used for generating binapi
- regenerate binapi with latest VPP release (19.04.1)
- change global variables Messages into a function AllMessages
