…iances in EnVar (#542) This PR modifies options (i_ensloccov4{scl,var,tim} -> r_ensloccov4{scl,var,tim}) to tune cross-scale/variable/time covariances in EnVar (#539). Regression tests for global 3dvar/4denvar/4dvar are not completed yet, but for other tests, issues are not found except for "failed the scalability test" and "exceeded maximum allowable hardware memory limit" on Orion.

In #460 and #504, scale/variable/time-dependent localization was introduced. However, factors multiplying to cross-scale/variable/time covariances have been forced to 0 or 1. To tune cross-scale/variable/time covariances more flexibly, options "i_ensloccov4{scl,var,tim}" (integer) are changed to "r_ensloccov4{scl,var,tim}" (real).
