chimera: change FileSystemProvider#move() return value meaning

FileSystemProvider#move() always returns true. Instead of changing
the interface let update the meaning and return true if underlying filesystem
was change and false if not. This is help to control attribute caching.

src: split nfs code info a dedicated module

we quite often need to update NFS code and it's much
simple if a new jar file contains only nfs changes.

There is a change, in pinning via nfs: it will
use DcapProtocolInfo to avoid dependency loop.
Matches current SRM behaviour.
