[Work in progress…] Generic file driver

[olivierlambert]

In order to benchmark and explore other file system alternative (XFS, ZFS, something else?), we are working on a "generic" SR driver, able to target a folder and… that's pretty much it. This way, you could:

• create a XFS mount
• use it as a local SR in XCP-ng

This will also open other possibilities, like separating pure "storage logic" to the hypervisor logic. However, you'll lose the possibility to manage your mount directly from XAPI, but it's not a big deal to start.
