Removing functionality in actions with v3, feedback welcome

Hi community :wave:

With v3, we are planning to remove large parts of the action functionality of preCICE as these are rarely used and hard to maintain.

Envisioned changelog entry:

  • Removed deprecated action timings regular-prior, regular-post, on-exchange-prior, and on-exchange-post.
  • Removed action timings read-mapping-prior, write-mapping-prior, and on-time-window-complete-post.
  • Removed ComputeCurvatureAction action.
  • Removed callback functions vertexCallback and postAction from PythonAction interface.

Previous functionality:

Please protest if you rely on any of this functionality.
