> Update quotaTypesEnabled on quota removal in ClientQuotaManager

> Priority: Major
> Fix For: 4.2.0
>
>
> In kafka.server.ClientQuotaManager class, quotaTypesEnabled is not updated
> when a quota is removed via removeQuota method in DefaultQuotaCallback class.
> This field is set when quotas are added in updateQuota but it's never changed
> or cleared. This can lead to incorrect behaviour in the quotasEnabled method.
> So in case all the quotas have been removed dynamically, the system may
> incorrectly assume the quotas are active, which leads to unnecessary metric
> creation or updates until the broker is restarted.
