The AWS waiter package has changed location in the 1.8.0 version of the
SDK. DMS will need to mitigate a breaking change because of this
Between @radeksimko and myself, we think that we should migrate the DMS
resources to using the Terraform state refresh func pattern that is used
across the entire of the AWS provider. DMS is the *only* resource that
currently uses the AWS waiters, so the LOE to migrate is pretty low
Fixes: #12506
When a replication_task cdc_start_time was specified as an int, it was
causing a panic as the conversion to a Unix timestampe was expecting a
string
