-- Creates an activity. An activity is a task that you write in any
-- programming language and host on any machine that has access to Step
-- Functions. Activities must poll Step Functions using the
-- @GetActivityTask@ API action and respond using @SendTask*@ API actions.
-- This function lets Step Functions know the existence of your activity
-- and returns an identifier for use in a state machine and when polling
-- from the activity.
--
-- This operation is eventually consistent. The results are best effort and
-- may not reflect very recent updates and changes.
--
-- @CreateActivity@ is an idempotent API. Subsequent requests won’t create
-- a duplicate resource if it was already created. @CreateActivity@\'s
-- idempotency check is based on the activity @name@. If a following
-- request has different @tags@ values, Step Functions will ignore these
-- differences and treat it as an idempotent request of the previous. In
-- this case, @tags@ will not be updated, even if they are different.
