> Project: Ignite

> Currently we have two methods to remove something from IGFS:
> 1) remove - performs soft delete for PRIMARY mode and hard delete for others
> 2) format - delete of all IGFS data without touching seocndary file system,
> which can be either soft or hard depending on some very coutner-intuitive
> conditions.
> I think we should do the following:
> 1) remove operation stays as is.
> 2) format method is deprecated and just falls-back to a new method
> "clear(ROOT)".
> 3) "clear" operation is semantically identical to cache clear: remove
> in-memory data, do not touch persistence layer. Essentially it just moves a
> tree into the trash just like remove does. But also this operation will offer
> sync and async modes. In sync mode operation exits when all in-memory data is
> really removed even from trash.
