/**
 * This function removed one or more zones from the active zoneset. This function will not
 * error if a zone to be removed was not found.
 * <p>
 * Removing zones typical flow is:
 * <ol>
 * <li>find the zones that can be deleted</li>
 * <li>get the session lock</li>
 * <li>delete the zones</li>
 * <li>commit which releases the lock</li>
 * <li>activate if requested</li>
 * </ol>
 * This flow is different when we're removing the last zones in a zoneset. If the zoneset becomes empty, it needs to be removed too or
 * commit would fail. In order to remove the zoneset, it has to first be deactivated. The flow for removing the last zones in a zoneset
 * is
 * <ol>
 * <li>find the zones that can be deleted</li>
 * <li>deactivate the zoneset</li>
 * <li>get the session lock</li>
 * <li>delete the zones</li>
 * <li>delete the zoneset</li>
 * <li>commit which releases the lock</li>
 * </ol>
