check_config() -> boolean()
Checks whether config parameters exist and are valid (requires a pull configuration, i.e. cloud_cps as cloud_module).
pull_scale_req() ->
{ok, Req :: integer()} | autoscale_error_resp()
Pull current scale request from autoscale leader. If the request is not 0, further requests should be locked with lock_scale_req/0 until a unlock_scale_req/0 call has been made. Autoscale defines a timeout, after which the lock will be automatically freed, i.e. the caller has $timeout seconds to satisfy the request and notify autoscale by unlock_scale_req/0.
