Andrey Kurilin 0a60aae852 Rename v1_1 to v2
Module novaclient.v1_1 is used as implementation of V1.1, V2 and V3.
Since future development(microversioning) will be done across V2,
implementation should be done in appropriate module(to prevent misleading).

Despite the fact that implementation for all versions are equal, discover
method for contrib path worked only for v1.1. This patch fixes this bug and
modifies shell tests to check all versions.
