Enables process tags propagation by default

[dubloom]

Description

Sets process tags config to true by default.

We set it to false by default in test, otherwise we would have to modify almost all the tests to add process_tags in them.

Tests that want to test the feature must activate it manually. For each product there is at least one test testing process tags (i.e activating the flag).

Reviewer checklist

• Test coverage seems ok.
• Appropriate labels assigned.
