Note that the WaiterModel takes ownership of the waiter_config.
It may or may not mutate the waiter_config. If this is a concern,
it is best to make a copy of the waiter config before passing it to
the WaiterModel.
:type waiter_config: dict
:param waiter_config: The loaded waiter config
from the <service>*.waiters.json file. This can be
obtained from a botocore Loader object as well.
