Remove open-discovery-services jar

[mandy-chessell]

Description

This PR reimplements the Atlas Discovery Service into an Atlas Survey Service. This was the last discovery service in the open-discovery-services.jar and so it has been removed.

All of the Atlas connectors are now gathered together in a separate jar called apache-atlas-connectors with is available through the distributions. The thought is that all of the connectors are likely to be used together or not at all so it was better to have them in one place rather than distributed across different jar files.

There have been some bug fixes made while testing this change:

• the admin call to add an integration group to a configuration document had a bug in its upsert logic that was corrupting the list of integration groups in the configuration document.
• The paging iterator in connectedAssetProperties was not updating its pointers correctly.

Release Notes & Documentation

Updates to docs have already been merged.

Additional notes

There are only two discovery services left in the egeria.git build. They are Coco Pharmaceuticals samples needed for the labs. Once they are rewritten to survey action services, the deprecation of the ODF, Asset Analysis OMES and Discovery Engine OMAS is complete.
