Add retry mechanism for Tempest functional tests

Registered by Valeriy Ponomaryov on 2014-12-20

We need to have "retry" mechanism for our tests in Tempest for case of some instabilities in infrastructure that is not related to functionality directly. For example, if we are testing something with shares and need to create share, but could not do it because of some low error. And it can be ok after second attempt. It should satisfy us, because we failed not on "tested" functionality, but on "pre_setup" that is not the goal of testing in many cases.

It will reduce false failures of gates.
