There were a couple of problems found by flake8 in the qa/
directory (most of them fixed now). Enabling flake8 during the usual
check runs hopefully avoids adding new issues in the future.

The helper gets a sequence number from the osd (or osds), and then
polls the mon until that seq is reflected there.
This is overkill in some cases, since many tests only require that the
stats be reflected on the mgr (not the mon), but waiting for it to also
reach the mon is sufficient!
