Add options to inflate the ensemble while recentering

[shlyaeva]

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.

Issues

Related to #1496 (doesn't fix yet since we need to decide what parameters to use this with)

Thanks @shlyaeva

Looks good to me ... as I learn C++

CI built this PR inside g-w develop. I forgot that g-w PR #3238 remains in review and has not yet been merged into g-w develop. I think GDASApp based g-w CI for marine DA is broken until g-w PR #3238 is merged into g-w develop.

Is this your understanding @guillaumevernieres ?

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