Attribute to enable tests with "shared resource" to run on same server within same "session".
This is primarily for the console test runner (or e.g engine mode "run all tests within automatically").
Scenario: I have some integration tests using large test data. This test data is created once and then reused between these tests. When using grid nodes tests using same "test data resource" might end up running in different grid nodes, causing each test creating new test data (which makes the tests slower than if they were run in serial).
It would be nice to have an attribute e.g. [SharedResource("TestBlob")] making all tests with same "shared resource" to be run within same grid node for the current "test run session".
