/// A RateLimitDescriptor is a list of hierarchical entries that are used by the service to
/// determine the final rate limit key and overall allowed limit. Here are some examples of how
/// they might be used for the domain "envoy".
///
/// .. code-block:: cpp
///
/// \["authenticated": "false"\], \["remote_address": "10.0.0.1"\]
///
/// What it does: Limits all unauthenticated traffic for the IP address 10.0.0.1. The
/// configuration supplies a default limit for the *remote_address* key. If there is a desire to
/// raise the limit for 10.0.0.1 or block it entirely it can be specified directly in the
/// configuration.
///
/// .. code-block:: cpp
///
/// \["authenticated": "false"\], \["path": "/foo/bar"\]
///
/// What it does: Limits all unauthenticated traffic globally for a specific path (or prefix if
/// configured that way in the service).
///
/// .. code-block:: cpp
///
/// \["authenticated": "false"\], \["path": "/foo/bar"\], \["remote_address": "10.0.0.1"\]
///
/// What it does: Limits unauthenticated traffic to a specific path for a specific IP address.
/// Like (1) we can raise/block specific IP addresses if we want with an override configuration.
///
/// .. code-block:: cpp
///
/// \["authenticated": "true"\], \["client_id": "foo"\]
///
/// What it does: Limits all traffic for an authenticated client "foo"
///
/// .. code-block:: cpp
///
/// \["authenticated": "true"\], \["client_id": "foo"\], \["path": "/foo/bar"\]
///
/// What it does: Limits traffic to a specific path for an authenticated client "foo"
///
/// The idea behind the API is that (1)/(2)/(3) and (4)/(5) can be sent in 1 request if desired.
/// This enables building complex application scenarios with a generic backend.
///
/// Optionally the descriptor can contain a limit override under a "limit" key, that specifies
/// the number of requests per unit to use instead of the number configured in the
