Rework the JS7 API for better consistency

Improvements

• The JS7 REST Web Service API requires improvements. Main pain points include:
  • inconsistent wording of web services
    • for example: /iam/identityservice/rename is in fact a replace operation
  • inconsistent wording of web service parameterization
    • for example: /inventory/repository/git/clone makes use of a remoteUri that in fact is a remoteUrl
  • inconsistent return values
    • properties in return values should carry the same names when used as parameters across a number of web services
  • inapplicable use of IDs
    • for example: /configurations, /configuration
  • missing input checks
    • a number of web services do not properly check parameterization
    • for example: /iam/identityservice/store does not check the ordering parameter
  • missing documentation
    • for example: /xmleditor, /configurations, /configuration
  • design problems
    • in order to hide an Agent the full Agent configuration has to be specified which is error-prone
    • in order to manage profiles the api for manage configurations is used. There should be CRUD operations with a profiles api directly.
• The JOC Cockpit GUI requires improvements for more efficient use of the API
  • when hiding an Agent then the GUI requests the list of all Agents to be stored
