Reduce Container Drag: generate a multi device server using chart based paramaters only (values.yaml)

This ticket arose from a problem workshop (see https://miro.com/app/board/o9J_koKNl68=/?moveToWidget=3074457349549897367&cot=12)

By reducing the number of containers and interprocess communication I have less need for a large execution environment for development. Changing inter processing to intra-processing communication should also reduce the latency involved in communicating between two parallel routines. 

The refactor of the tango-util library helm chart has been completed, and the tango example has been refactored to use it. Documentation is available here https://developer.skatelescope.org/projects/ska-tango-images/en/latest/helm_charts.html#the-tango-util-helm-chart . Also, the changed library has been integrated with Skampi but the new features have not been activated. This will need to be done by each team.
