Enable pretty-printing output by default, create configuration option to disable pretty-printing

Feature request from Ironbank:

When you print the values, it does it as a blob instead of pretty printing Can you pretty print?

By default, output is currently a giant blob. This is required for the parsers that power the Grafana dashboards as part of the Cron Job chart. This is a lesser user experience on the command line however. Traditionally, we've asked that users pipe that output to another tool like jq or yq for formatting, however this is less intuitive for new users and doesn't really enhance the user experience. Instead, we should enable pretty-printing by default and have it disabled in the helm chart where necessary.

Acceptance Criteria

• Implement pretty-printing for YAML and JSON structured outputs
• Create a configuration flag to enable pretty printing
• Set the flag to True in new configuration files by default. If the flag is not set, False.
• Update the Helm charts to explicitly disable pretty printing
• Detect if the output is being piped into another program and if so, disable pretty printing
