> Add an option to add a prefix on Kubernetes resources

> Key: NIFI-12590
> URL: https://issues.apache.org/jira/browse/NIFI-12590
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Affects Versions: 2.0.0-M2
> Reporter: Julien G.
> Assignee: Julien G.
> Priority: Major
> Time Spent: 4h 10m
> Remaining Estimate: 0h
>
> In case of using Kubernetes as a *Cluster Leader Election* and *State
> Mangement*, NiFi will create two types of resources: *ConfigMaps* and
> *Leases*.
> 2 *Leases* for the _Cluster Leader Election_ and multiple *ConfigMaps*
> depending the number of components which their state to be stored.
> Their names are normalized:
> - *Leases*: {{cluster-coordinator}} and {{primary-node}}.
> - *ConfigMap*: {{nifi-component-%s}} with {{%s}} the component identifier.
> But currently, if someone wants to deploy more than one cluster in one
> namespace, conflicts will arise. Because the resources will share their
> names. It has been done this way to prevent security concerns where a cluster
> will manipulate resources of another cluster.
> But as discussed on Slack, these concerns can't prevented with 100% certainty.
> So users should be able to configure a prefix to add to these resources to
> prevent conflict and assume the security concerns.
> It can be done by replicating the logic done with ZooKeeper by adding a
> property in {{nifi.properties}} and a new field in the
> {{state_management.xml}} file.
