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.

aa4622cc01 Make core remove error recoverable 
First try to clean only the mapping. This operation does not require any
rollback, so even if flushing collision fails, core object is still
intact. In case of error we inform user that core was not removed by
returning new error code (-OCF_ERR_CORE_NOT_REMOVED).

After flushing collision succeeds we remove core from metadata and
flush superblock at the end. At that point the core is fully removed
from OCF and even if superblock flush error occurs there is nothing we
can do about it, so we just return the error code.
