test: add a test file for relevant obsmarkers and its usage

The logic around obsmarkers "relevant" to a set of revs have a couple of test
around in other places but no systematic testing. In addition, all the current
testing focus on the exchange case (we looks at relevant markers for
'::heads').

For bundles, we'll need something a bit different. We'll no longer have set of
revision going down to the repository roots. So we'll have to test these cases
too. In addition, stripping obsmarkers will introduce new logic around
obsmarkers that will need testing too. So a new test file make sense here.

We start with a simple tests, more advanced cases are coming in the next
changesets. The extra testing catch a minor bug (later in the series).
