/// Creates a L7 rule.
///
/// This operation provisions a new L7 rule by using the configuration that you
/// define in the request object. After the API validates the request and
/// starts the provisioning process, the API returns a response object that
/// contains a unique ID and the status of provisioning the L7 rule.
///
/// In the response, the L7 rule [provisioning status](#prov-status) is
/// `ACTIVE`, `PENDING_CREATE`, or `ERROR`.
///
/// If the status is `PENDING_CREATE`, issue GET
/// `/v2/lbaas/l7policies/{l7policy_id}/rules/{l7rule_id}` to view the progress
/// of the provisioning operation. When the L7 rule status changes to `ACTIVE`,
/// the L7 rule is successfully provisioned and is ready for further
/// configuration.
///
/// If the API cannot fulfill the request due to insufficient data or data that
/// is not valid, the service returns the HTTP `Bad Request (400)` response
/// code with information about the failure in the response body. Validation
/// errors require that you correct the error and submit the request again.
///
/// All the rules associated with a given policy are logically ANDead together.
/// A request must match all the policy’s rules to match the policy.
///
/// If you need to express a logical OR operation between rules, then do this
/// by creating multiple policies with the same action.
