Request customizing based on the code list reference given in the entity container's
given <code>com.sap.vocabularies.CodeList.v1.*</code> annotation.

@param {string} sTerm
  The unqualified name of the term from the <code>com.sap.vocabularies.CodeList.v1</code>
  vocabulary used to annotate the entity container, e.g. "CurrencyCodes" or "UnitsOfMeasure"
@param {any} [vRawValue]
  If present, it must be this meta model's root entity container
@param {object} [oDetails]
  The details object
@param {sap.ui.model.Context} [oDetails.context]
  If present, it must point to this meta model's root entity container, that is,
  <code>oDetails.context.getModel() === this</code> and
  <code>oDetails.context.getPath() === "/"</code>
@returns {Promise}
  A promise resolving with the customizing which is a map from the code key to an object with
  the following properties:
  <ul>
    <li> StandardCode: The language-independent standard code (e.g. ISO) for the code as
      referred to via the <code>com.sap.vocabularies.CodeList.v1.StandardCode</code>
      annotation on the code's key, if present
    <li> Text: The language-dependent text for the code as referred to via the
      <code>com.sap.vocabularies.Common.v1.Text</code> annotation on the code's key
    <li> UnitSpecificScale: The decimals for the code as referred to via the
      <code>com.sap.vocabularies.Common.v1.UnitSpecificScale</code> annotation on the code's
      key; entries where this would be <code>null</code> are ignored, and an error is logged
  </ul>
  It resolves with <code>null</code>, if no given
  <code>com.sap.vocabularies.CodeList.v1.*</code> annotation is found.
  It is rejected, if there is not exactly one code key, or if the customizing cannot be
  loaded.
@throws {Error}
  If <code>vRawValue</code> or <code>oDetails.context</code> are present, but unsupported
