KIP-546 — Add Client Quota APIs to the Admin Client

Accepted Kafka 2.6 Admin

Adds dedicated `describeClientQuotas()` and `alterClientQuotas()` methods to `AdminClient` with a rich quota entity model supporting entity types (user, client-id, IP) and quota types (produce rate, consume rate, request percentage, connection rate). Managing quotas via the existing `describeConfigs`/`alterConfigs` APIs is awkward because quotas do not fit the key-value config model and the APIs cannot return all quota metadata (e.g., which entity types have quotas applied).
