Fix regression, make sure if period is not supplied to ArchiveInvalidator then all periods are invalidated efficiently.

https://github.com/piwik/piwik/pull/8857

We cannot let tracking fail under any circumstance, but with STRICT_TRANS_TABLES, when a plugin is disabled, and the column is NOT NULL, then tracking would fail.

 Fixes #8853

Remove need for TableLogAction\Cache::$hits property which is only used for tests by injecting cache implementation used and using mock in test.

Added INI setting to configure maximum number of id actions to store in one cache entry + integration tests

Caching id actions in general cache - can be enabled via INI setting enable_segments_subquery_cache setting (disabled by default)

Move date parsing logic from ArchiveInvalidator to CoreAdminHome/API.php so the service class only accepts well formed input.

Add event that allows plugins to archive data even if there are no visits for the period. Undocumented for now.

Allow Segments to define multiple SQL columns if the segment value can be matched in any of those fields, and use to define two new segments: customVariableName & customVariableValue.
