-- Lists the high-availability partition groups for the account.
--
-- This operation supports pagination with the use of the @NextToken@
-- member. If more results are available, the @NextToken@ member of the
-- response contains a token that you pass in the next call to @ListHapgs@
-- to retrieve the next set of items.
--
-- This operation returns paginated results.
