Refactor API.getSegmentsMetadata and Plugin\Segment so segments are all defined through Plugin\Segment class in dimensions & make sure AutoSuggestAPITest data providers do not use database.

Update misc/log-analytics repo for https://github.com/piwik/piwik-log-analytics/issues/67 and update expected test output.

Add expanded query param to DocumentationGenerator so the API test generation logic will not erase the param from API tests.

Make userId segment work for all operators (Is, is not, contains, does not contain, is null, is not null)
fixes #8062
this reverts https://github.com/piwik/piwik/commit/252798d2d742cae998a1f42f50a5ba37c98069df

Also adds a missing URL Encoding for action URLs.
(when outlink or download urls contained `&` and such characters breaking the URL this possibly corrupted the tracking request).

Fixes #6244

As the plugin does now nothing anymore, I removed it.

Refs https://github.com/piwik/piwik-log-analytics/issues/68, add tests for replay logging including logs w/ error statuses, and update log-analytics repo.
