-- 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.
