/// Creates a health monitor on a pool.
///
/// Health monitors define how the load balancer monitors backend servers to
/// determine if they are available to service requests.
///
/// This operation provisions a new health monitor 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 health monitor.
///
/// In the response, the health monitor [provisioning status](#prov-status) is
/// `ACTIVE`, `PENDING_CREATE`, or `ERROR`.
///
/// If the status is `PENDING_CREATE`, issue GET
/// `/v2/lbaas/healthmonitors/{healthmonitor_id}` to view the progress of the
/// provisioning operation. When the health monitor status changes to `ACTIVE`,
/// the health monitor 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.
///
/// Specifying a project_id is deprecated. The health monitor will inherit the
/// project_id of the parent load balancer.
///
/// At a minimum, you must specify these health monitor attributes:
///
/// Some attributes receive default values if you omit them from the request:
///
/// To create a health monitor, the parent load balancer must have an `ACTIVE`
/// provisioning status.
