Since Ia1a0066dc30025c02553584a077365b28d8ff80e FilterScheduler will
no longer fall back to not using placement API. We need to require
version 1.4 to prevent NoValidHost errors.

In Ocata, the filter scheduler would not consult placement until all of
the computes had been upgraded. That check no longer makes sense in Pike
and isn't multi-cell-aware anyway. This removes that check.
