bookmark: introduce a 'bookmarks' part

This part can carry and apply bookmarks information. We start with adding the
core behavior of the part. In its current form, the part is only suitable for
push since it plain update the bookmark without consideration for the local
state. Support of the behavior needed for pulling will be added in later
changesets.
