Quarantine flaky storage test that starts VMI with faulty disk

The following test has been impacting the storage test lanes over the
past two weeks:

`Storage Starting a VirtualMachineInstance with faulty disk [It] should
pause VMI on IO error`

As the impact has been greater than 5% over the past 14 days[1], this test
qualifies for quarantine.

This test may also be impacting another storage test[2] so quarantining
will allow to see if this helps to reduce the flakiness.
