Fix multiple usages of waiters
Fix consists of 2 parts: - Calculate correctly left time for waiting in 'scale_dcs_pod_amount_and_wait' function. Before, it had bug, where we were waiting less time than requested. And it led to the unexpected timeout errors. Example: it could fail waiting only 180sec having 600sec as real timeout. - Reset 'attempts' on the instantiated 'waiter's to avoid redundant waiting reusing the single waiter instance. Example. On deletion of 20 PVCs we save about 1,5 minutes. In whole test suite we create much more PVCs than 20. Change-Id: I5d06a63dd0c2c5bd67fdb09fef87948d65e6bf22
