I note that this file could be greatly reduced via anchors and aliases because the plugins all share a large set of parameters.

I can do this work but it might be instructive for someone else to take it on an learn about anchors and aliases which are a nice way of making YAML DRY.

See my example in this MR https://gitlab.diamond.ac.uk/controls/containers/beamline/b01-1-services/-/merge_requests/56#note_120866 (this is for ioc.yaml - but similar things can be done in the support.yaml).

@OCopping @GDYendell @callumforrester @jsouter @JamesOHeaDLS FYI - any volunteers?
