precice: new package (issue #8643) (#8644)

preCICE (Precise Code Interaction Coupling Environment) is a
  coupling library for partitioned multi-physics simulations.
  Partitioned means that preCICE couples existing programs (solvers)
  capable of simulating a subpart of the complete physics involved in
  a simulation.
