test: add a test file dedicated to an important distributed case
This test file introduce documented test case for obsolescence markers usage
that are important to distributed workflow cases.
In the distributed case, new changesets, markers, and phases can be added in
orders that would not happen during the local only usage. Documenting these
scenarios and test them is important as we make progress with various
obsolescence aspect.

+=============================
+Test distributed obsolescence
+=============================
+
+This file test various case where data (changeset, phase, obsmarkers) is added
+to the repository in a specific order. Usually, this order is unlikely to
+happen in the local case but can easily happen in the distributed case.

+Check distributed chain building
+================================
+
+Test case where a changeset is marked as a successor of another locally
+changeset while the successor has already been obsoleted remotely.
+
+The chain of evolution should seamlessly connect and all but the new version
+(created remotely) should be seen as obsolete.
