Description:

Changes:

• rename PluginSetting component to GroupedSetting (changed :plugin-name to :group-name and allow it to be optional)
  This component encapsulates the Vue side handling of the formField.condition parameter in angularjs, but in a way that doesn't require FormField to know about every other setting/setting value. It's used in measurable settings and tag manager parameters.
• refactored condition handling to take place in GroupedSetting instead of FormField to reduce the amount of work FormField does and so we don't have to pass a dynamic function as a property to FormField and so FormField doesn't have to show/hide itself. BC w/ angularjs should still be maintained.

@sgiehl @peterhashair it would be good to review this one before doing the sitesmanager PRs.

Review

• Functional review done
• Potential edge cases thought about (behavior of the code with strange input, with strange internal state or possible interactions with other Matomo subsystems)
• Usability review done (is anything maybe unclear or think about anything that would cause people to reach out to support)
• Security review done
• Wording review done
• Code review done
• Tests were added if useful/possible
• Reviewed for breaking changes
• Developer changelog updated if needed
• Documentation added if needed
• Existing documentation updated if needed
