When using default.yml to add configuration, empty keys aren't added to config files

When using default.yml to add configuration, empty keys aren't added to config files

This can be interesting for example for adding empty serverclasses.

Example:

splunk:
	conf:
		serverclass:
			directory: /opt/splunk/etc/system/local
			content:
				global:
					targetRepositoryLocation: $SPLUNK_HOME/etc/apps
					disabled: false
					excludeFromUpdate: "$app_root$/.git*"
					"serverClass:secrets": 
						repositoryLocation: /etc/splunk/secrets
					"serverClass:secrets:app:test": {}
					"serverClass:secrets:app:*": []
					"serverClass:secrets:app:universal_secrets":
						"whitelist.0": "*splunk-ingester*"

results in

[serverClass:secrets:app:test]
[serverClass:secrets:app:*]

missing in /opt/splunk/etc/system/local/serverclass.conf after.

Possible workarounds:
Create non-empty keys where possible.

Include files or apps instead of using using the config option in default.yml

Not sure if the formatting got messed up, but I assume the default.yml is supposed to look like:

splunk:
  conf:
    serverclass:
      directory: /opt/splunk/etc/system/local
      content:
        global:
          targetRepositoryLocation: $SPLUNK_HOME/etc/apps
          disabled: false
          excludeFromUpdate: "$app_root$/.git*"
        "serverClass:secrets":
          repositoryLocation: /etc/splunk/secrets
        "serverClass:secrets:app:test": {}
        "serverClass:secrets:app:*": []
        "serverClass:secrets:app:universal_secrets":
          "whitelist.0": "*splunk-ingester*"
...

The serverClass:secrets:app:test should be at the same level as global correct? Otherwise, it may not be treating it as a section as intended.

I had to re-intend before copy pasting, I made a mistake there, sorry,

In the testing it was all at the same level as this serverclass, and the ones with the whitelist like below, did get rendered:

"serverClass:secrets:app:universal_secrets":
          "whitelist.0": "*splunk-ingester*"

This will be solved by #446 - we'll get this in splunk/splunk:8.0.3
