features/bit-rot-stub: bring in optional versioning

Browse Source 
* As of now bit-rot-stub does versioning always. This leads
  lots of getxattr calls being made in lookups. So make
  object versioning optional.

/* TODO:
* As of now enabling bitrot option does 2 things.
* 1) Start the Bitrot Daemon which signs the objects (currently files only)
* upon getting notified by the stub.
* 2) Enable versioning of the objects. Object versions (again files only) are
* incremented upon modification.
* So object versioning is tied to bitrot daemon's signing. In future, object
* versioning might be necessary for other things as well apart from bit-rot
* detection (well thats the objective of bringing in object-versioning :)).
* In that case, better to make versioning a new option and letting it to be
* enabled despite bit-rot detection is not needed.
* Ex: ICAP.
