server: Use standard IMarker structure for storing bookmarks

The new changes aim to re-structure the algorithm of storing bookmarks.
Previously, we stored each bookmark (of an experiment) under a specific
directory inside the .webapp directory of Trace Compass. Right now, we
are using Eclipse's markers system to store and fetch the benchmarks.

[Changed] Bookmark storing/fetching system is changed to IMarker
