Major project restructuring

Our project was getting pretty untidy, so we moved some things around and renamed some things to fit community naming standards.

If you used the toolkit prior to this version, odds are your stuff will now be broken.

• atlas cli has been moved into its own repository: https://github.com/infobloxopen/atlas-cli
• collection_operators.proto file moved from /op to query
• auth interceptor can now be imported from github.com/infobloxopen/auth and is called auth.UnaryServerInterceptor
• collection operators middleware can now be imported from github.com/query and is called query.UnaryServerInterceptor
• gorm functionality now lives in its own package, /gorm so while none of the function names were changed the import path is changed
