obsstore: add fields attribute to track each field in a marker

We are going to increase the amount of data explicitly stored in obsolescence
markers. This mean we are going to have a longer tuple and some values will be
shuffled around. So we add a ``fields`` attribute to the obsstore class to
keep track of what entry is what. This will be useful for extensions and for
documentation purpose.
