docs: Create Prefixed request headers which are appropriate for Azure.
  
  If the request header is appropriate for Azure (e.g. Cache-Control) then it should be
  passed along without a metadata prefix. For all other request header parameter names,
  qq.azure.util.AZURE_PARAM_PREFIX should be prepended.
  
  @param name Name of the Request Header parameter to construct a (possibly) prefixed name.
  @returns {String} A valid Request Header parameter name.
