Description:

The core:archive command provides a flag --skip-segments-today, which prevents segments data from being processed for today.

The currently implementation only prevents them from being processed. But invalidation done for today before archiving is started is currently done anyway. This causes also the higher periods (week, month, year) to be invalidated. But as only today is prevented from being archived for segments, those higher periods will be reprocessed anyway, even if there actually were no changes in lower periods.

To prevent this unnecessary archiving of those higher periods, this PR changes the behavior of the initial invalidation. If --skip-segments-today is provided, we will no longer create invalidations for segments for today (and periods including this day).
This shouldn't cause any problems even if the flag is used always when archiving is triggered, as yesterday will still be invalidated for segments.

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
