#2950: CarpetX/ADMBaseX: Missing ADMBase features (Conditional storage, evolution parameters)

Reporter: Maxwell Rizzo Status: new Milestone: Version: Type: bug Priority: minor Component: CarpetX

Very similar to #2948, but smaller in scope. Mostly consistency and future proofing in mind. All changes are following the previous Carpet ADMBase conventions.

1. Missing conditional storage on the extra fields (shift, dtlapse, dtshift). 2. Missng `*_evolution_method` parameters specifying which thorn evolves which fields. 3. ADMBaseX defaults to an initial dtlapse/dtshift of `zero` instead of `none` (previously in Carpet ADMBase). With conditional storage it probably makes sense to return to the `none` default to only enable the extra fields if the user needs them. Changing this default here may break some test parameter files.

Addressed by CarpetX [PR #386](https://github.com/EinsteinToolkit/CarpetX/pull/386)
