transaction: track new obsmarkers in the 'changes' mapping

The obsstore collaborate with transaction to make sure we track all the
obsmarkers added during a transaction. This will be useful for various usages:
hooks, caches, better output, etc.

This is the seconds kind of data added to tr.changes (first one was added revisions)
