Correct @RussTreadon-NOAA . We need to wait for #3238 ... I keep forgetting. |

# Description Adds code to the ensemble recentering to optionally inflate/deflate the ensemble variance by either a scalar (same for all variables) or a field from the file (has to be specified for all variables).

Description
Adds code to the ensemble recentering to optionally inflate/deflate the ensemble variance by either a scalar (same for all variables) or a field from the file (has to be specified for all variables).
This is not exercised yet, since we don't know the parameters of inflation/deflation yet, but I tested with both options to check whether it behaves as expected.
Note: in the future refactoring we should switch to oops::Inflation that provides several different inflation options.
