4fd2b22b69 Make allocating field names avoidable for range and exists queries. 
If the field names are statically known, `Cow::Borrowed(&'static str)` can
handle them without allocations. The general case is still handled by
`Cow::Owned(String)`.

/// of the number of different values in a data set based on the
/// HyperLogLog++ algorithm. This is particularly useful for understanding the
/// uniqueness of values in a large dataset where counting each unique value
/// individually would be computationally expensive.
///
/// For example, you might use a cardinality aggregation to estimate the number
/// of unique visitors to a website by aggregating on a field that contains
/// user IDs or session IDs.
///
/// To use the cardinality aggregation, you'll need to provide a field to
/// aggregate on. The following example demonstrates a request for the cardinality
/// of the "user_id" field:
///
/// ```JSON
/// {
/// "cardinality": {
/// "field": "user_id"
/// }
/// }
/// ```
///
/// This request will return an estimate of the number of unique values in the
/// "user_id" field.
///
/// ## Missing Values
///
/// The `missing` parameter defines how documents that are missing a value should be treated.
/// By default, documents without a value for the specified field are ignored. However, you can
/// specify a default value for these documents using the `missing` parameter. This can be useful
