EZP-23825: integrated the tracker via a Response Event

[bdunogier]

EZP-23825
Status: ready for review

Adds a ResponseListener that adds the tracker before the </body> tag.

TODO

• Test if TrackingSettings.AutomaticTracking is enabled (later)
• Inject legacy settings into the listener
• Document (in README.md)
• Test listener
• Test factory

Ok, so we add it in event instead of documenting how to add it in templates basically. Any pitfalls with this? Will it fail in some cases? Like add it if a REST api has a tag called body?

[bdunogier]

Note that it is how it was done in the legacy one (via a response filter).

It also prevents maintainers from having the installation_id in two places. But yes, there might be edge cases such as the one you describe.

Maybe we could also test the Response content-type for text/html ?
