Support deployment of Parameter Providers

[ChrisSamo632]

Is your feature request related to a problem?

Sensitive Parameters are often best managed externally from NiFi, where they can be better protected (and/or shared with outher applications as appropriate).

Describe the solution you'd like to see

NiFi allows for the use of Parameter Providers in order to externalise sensitive parameters, e.g. as Kubernetes Secrets, AWS Systems Manager Parameters, AWS Secrets, etc.

Adding the ability to configure Parameter Providers as part of a NiFi Cluster deployment by NiFiKop could help with secure and configurable deployments, particularly in multi-environment setups.

Describe alternatives you've considered

• Manually configuring the Parameter Providers within the deployment
• Using NiFi Toolkit/NiPyApi to script the connectivity as part of a post-deployment Job

At some point, when the feature was released, I thought of implementing it but I never had the time to do it. But it sure a feature that is interesting to implement.

The Kubernetes Secrets is in someway already usable with the NifiParameter resource and its secretRef field.
