Change subject: KUDU-3002: prioritize WAL unanchoring when under memory pressure
......................................................................

> Forgot to mention: could you sanity check this on a real cluster?

Tested on a real cluster with a 1% memory pressure limit and 1GiB hard limit, 
with a constant insert loadgen workload and manual upserts.

I eventually saw DMS flushes a few seconds after upserting (i.e. the DMS 
flushes are not being triggered immediately, just when they become "old" enough 
to unanchor WALs).
