-- Returns the status of a 'ChangeToken' that you got by calling < GetChangeToken>. 'ChangeTokenStatus' is one of the following values:
--
-- -   'PROVISIONED': You requested the change token by calling 'GetChangeToken', but you haven\'t used it yet in a call to create, update, or delete an AWS WAF object.
-- -   'PENDING': AWS WAF is propagating the create, update, or delete request to all AWS WAF servers.
-- -   'IN_SYNC': Propagation is complete.
