Refactor driver interfaces

Registered by Julia Portnova

Currently we have three interfaces in driver:
1. allocate container
2. create share
3. create export

Not all the backends need to implement of those three interfaces.

The proposal is to have one interface create_share.
We will need to modify base driver and all the backends.

Caitlin Bestler:

It is easy to envision folding explicit creation of containers into being something implicit as a result of creating shares. But how do you make control of visibility implicit? Would you still be able to temporarily hide, but not erase, a share?
