//! Set the state of members for a pool in one API call. This may include
//! creating new members, deleting old members, and updating existing members.
//! Existing members are matched based on address/port combination.
//!
//! For example, assume a pool currently has two members. These members have
//! the following address/port combinations: ‘192.0.2.15:80’ and
//! ‘192.0.2.16:80’. Now assume a PUT request is made that includes members
//! with address/port combinations: ‘192.0.2.16:80’ and ‘192.0.2.17:80’.
//!
//! The member ‘192.0.2.15:80’ will be deleted, because it was not in the
//! request.
//!
//! The member ‘192.0.2.16:80’ will be updated to match the request data for
//! that member, because it was matched.
//!
//! The member ‘192.0.2.17:80’ will be created, because no such member existed.
//!
//! The optional parameter `additive_only` when defined as `true` will skip
//! deletions for members missing from the provided list. If this were set in
//! the above example, the member ‘192.0.2.15:80’ would have remained in the
//! pool.
//!
//! If the request is valid, the service returns the `Accepted (202)` response
//! code. To confirm the updates, check that the member provisioning statuses
//! are `ACTIVE` for new or updated members, and that any unspecified members
//! were correctly deleted. If the statuses are `PENDING_UPDATE` or
//! `PENDING_DELETE`, use GET to poll the member objects for changes.
