1bdf4a13ae pyocf: Improve volume instance lifecycle handling 
We need a strong reference to volume for as long as OCF has it open.
For that I changed instance tracking dictionary from weakvalue to
normal. This way I made sure that GC won't clean up Volume before its
closed.

9739a442b6 [pyocf] properly resolve volume type 
OCF volume type is different for each context in which given
type (Volume subclass) is registered. So OCF volume type should
not be a Volume subclass member.

Adding map in Context class to store OCF volume type for each
registered volume type.
