Release 2021.08.02

Upgrade instructions

From #2805 (The transformation between the inertial coordinates and the Cauchy coordinates in CCE):

The feature is controlled by uses_inverse_coordinates of CCE metavariables.

From #3279 (Horizon finder in grid frame):

One must now specify compute_vars_to_interpolate instead of compute_items_on_source for interpolation that uses the Interpolator ParallelComponent.
