Streamline github actions

[milenkovicm]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.

Github actions look very busy, and repeatable (multiple actions do same check), on top of that they need 25+ mins to finish.
rust compilation is done in dedicated rust container.

There is no clean difference between "Test Workspace ..." & "Test Ballista" ...

Also, some of the actions are complaining about deprecations.

Describe the solution you'd like

streamline and modernise github actions file, use github action for rust setup, build caching ... . remove options which are not used anymore.

Describe alternatives you've considered
