Hello Mike Percy, Jean-Daniel Cryans, Kudu Jenkins, Todd Lipcon,
I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).
Change subject: KUDU-2238. DMS not flush under memory pressure.
......................................................................
KUDU-2238. DMS not flush under memory pressure.
When we choose DMS to flush, now we always pick the DMS with
highest log retention. However, as KUDU-2238 shows, in some cases
DMS with highest log retention may only consume little memory, and
other DMSs may consume much more memory, but get no chance to be
flushed, even under memory pressure.
This patch gives the ability to take memory consumption into
consideration when we choose DMS.
