NIFI-9183: Add a command-line option to save status history

[Lehel44]

Thank you for submitting a contribution to Apache NiFi.

Please provide a short description of the PR here:

Description of PR

Added command-line option to save status history in JSON.

Details

When you run nifi.sh with a command line option, the RunNiFi class parses the options, creates a NiFi server instance, and sends a request to the BootstrapListener on the server. Objects from nifi-core can be injected by spring web context. Since only a single NiFiServer instance can be accessed in BootstrapListener, I extended it with a new method that returns the status history.

• Outsourced StatusHistoryRepository creation to a factory bean from FlowController in order to use it in nifi-runtime.
• The NiFiServer interface has been extended with the String getNodeStatusHistoryJson(final int days); method. (Returns a string in order to avoid additional dependencies in nifi-bootstrap. Dependencies in nifi-runtime affect nifi-bootstrap as well, and they must be added to assembly/common.xml filters.)
• Extended RunNiFi and nifi.sh with the new status-history option.
• The StatusHistoryRepository gets injected into JettyServer which can be accessed by NiFiBootstrap.

Still under consideration or work in progress:

• NiFiServer: default vs not default method?
• Extend admin guide
