[RTA/DPA BW tests]: Temporarily allow error code 1 for process = hlt2 in bw tests
FYI @lugrazet
Goes with lhcb/Moore!3644 (merged), lhcb-datapkg/PRConfig!433 (merged) and LHCbNightlyConf!1254 (merged)
When we move the tests to real data in the above MRs we'll get ERROR messages due to Misordered Large Clusters
that we can't do anything about, but they aren't harmful. We ignore them in the Moore qmtest, but they'll give an error code of 1, so we have to ignore them here to make sure the bandwidth tests give "success" messages even if they hit this.
Testing fine for me locally.
