    Enable debug log for FluxCD controllers

    We are missing some information about what FluxCD does internally. This
    information helps us investigate issues related to StarlingX apps.

    Experiments showed debug prints are produced only when FluxCD is
    instructed to change state by the StarlingX app framework (app
    operations are sparse operations).
    With the above in mind enable debug log level.

    Also switching log format from json:
    {"level":"info","ts":"2022-10-27T19:16:22.768Z","logger":"controll...
    to a more familiar format:
    2022-10-27T19:19:26.218Z INFO controller.helmchart Reconciliation...

    Tests on AIO-SX:
    PASS: unlocked enabled available
    PASS: visual inspected logs
