/// Creates a pool for a load balancer.
///
/// The pool defines how requests should be balanced across the backend member
/// servers.
///
/// This operation provisions a pool 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, which contains a
/// unique ID.
///
/// In the response, the pool [provisioning status](#prov-status) is `ACTIVE`,
/// `PENDING_CREATE`, or `ERROR`.
///
/// If the status is `PENDING_CREATE`, issue GET `/v2/lbaas/pools/{pool_id}` to
/// view the progress of the provisioning operation. When the pool status
/// changes to `ACTIVE`, the pool is successfully provisioned and is ready for
/// further configuration.
///
/// At a minimum, you must specify these pool attributes:
///
/// Some attributes receive default values if you omit them from the request:
///
/// 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 pool will inherit the project_id
/// of the parent load balancer.
///
/// You can configure all documented features of the pool at creation time by
/// specifying the additional elements or attributes in the request.
///
/// To create a pool, the parent load balancer must have an `ACTIVE`
/// provisioning status.
