Implement a graphql query and resolver that allows the UI to retrieve the compiled schema from the admin server. There exists POC that should have all the relevant bits, but the feature should be implemented on the master branch.

To compile the schema something like this can be used: https://github.com/pb82/data-sync-ui/blob/schema-editor/server/gql/helper.js

The query and resolver should be added here: https://github.com/aerogear/data-sync-ui/blob/master/server/gql/schema.js

Something like this can be used for sequelize to store the schema: https://github.com/pb82/data-sync-ui/blob/schema-editor/server/models/schema.js
