Handle 100 policies per principal issue

[sodre]

While running in production we ran into the following problem during initialization:

{APP} 2023-07-17 14:39:39,187 ERROR [main] c.z.n.a.c.CognitoNaiveAccessPolicyProvider Error adding principal 'grp:e8f9d592-31f9-19fb-d58d-82fe85ebbb22' to group 'identifier[e44031ed-5758-4582-9e0f-1c115da24b0a], resource[/controller], users[[ef5a965d-7bd2-ef33-21de-c444c40e462a]], groups[[e8f9d592-31f9-19fb-d58d-82fe85ebbb22, 1ce4d21a-5c20-4c1b-bc7d-f52ff5dbd792]], action[read]'
software.amazon.awssdk.services.cognitoidentityprovider.model.LimitExceededException: The limit for addUserToGroup is: 100. (Service: CognitoIdentityProvider, Status Code: 400, Request ID: 80f36c77-ac51-439d-b8ef-00204e7ad315)

The issue is that a Cognito User/Principal can belong to at-most 100 groups. This is a hard quota that can't be modified according to AWS documentation. See Quotas on resource number and size here.

This limit seems large enough, but because a NiFi AccessPolicy is encoded as a Cognito Group we can reach that limit quickly once the number of clusters goes above ~10.
