David Disseldorp a1d11eb0f9 test: move UA drain helper function into iscsi-support
test_iscsi_tur_until_good() dispatches TUR requests until the target has
cleared all UAs for the given sd, or the maximum number of retries is
reached.
This helper function is useful for any test that needs to deal with UAs
(e.g. PRs), so should be moved out into common code.
