Tests from zaqar.tests.unit.transport.websocket.v1_1 do not execute(and fail if made executed)

[Eva Balycheva]

I noticed that subscriptions over websocket do not work. (!)
It made me wonder how tests related to subscriptions pass.
Then I figured out that the test class:
"zaqar.tests.unit.transport.websocket.v1_1.test_subscriptions.SubscriptionTest"
doesn't execute via tox at all.

It doesn't execute, because testr can't find this test.
And testr can't find this test, because the directory: "zaqar/tests/unit/transport/websocket/v1_1"
doesn't contain "__init__" file.

When I add "__init__" file, tox finds test class and executes it, but 4 of 5 test cases fail.

    Move subscription test from v1_1 to v2

    subscription is supported since v2, so it's not reasonable to keep
    a test under v1_1.
