Based on the feedback from the presentation of this feature, we would like a mechanism to support bulk migrating indices to continuous. The change policy API does support wildcards, but it requires a policyID in the request, so users can only bulk change indices to be continuous if the policies are set as well.

Before this feature is released, let's do a minor refactor to allow null policyID values in a ChangePolicyRequest if there is a continuous field present.
