Review request for hbase and stack.
Changes
-------
Makes DeadServers private. It was still accessed by my TestRollingRestart test
so I had to make a small change to how that worked.
Also added some additional testing in TestDeadServers that verifies the new
boolean check works as expected and also that the max capacity works as
expected.
Summary
-------
We currently let go of dead servers once we finish their shutdown. We should
hang on to them longer to deal with things like network partitions.
I'm not a fan of SoftReferences so I decided on another approach. DeadServers
now has a maximum number of servers to hold on to in the set (default 100).
Once it reaches the max, it evicts the oldest.
More code than I had hoped but nothing too crazy.
This addresses bug HBASE-3282.
