1039 reduce collection rate, changed 10m->30m 1s->2s
Handle bad request (400) by stopping further scheduling of MLS queries.
We decided to delete stumbles on 400 (bad request) errors only, in that
in theory other errors, particularly 404 can be temporary and
incorrectly returned by proxies. I am trying to minimize the
possibilities of stumbles being disposed due to complaints about data
disappearing that we have no other possibilities for at this time.
