+- improvement to obsolescence marker exchange:
+  - record parent of pruned parent at prune time
+  - added progress when pushing obsmarkers
+  - added multiple output during obsolescence markers exchange
+  - only push markers relevant to pushed subset
+  - add a new experimental way to exchange marker (when server support):
+    - added progress when pulling obsmarkers
+    - only pull markers relevant to pulled subset
+    - avoid exchanging common markers in some case
