Force all

@agorrod Please review this.  It contains moving the one line for the aggressive we talked about last night.  I added the LSM table name to a bunch of verbose output.  I added a loop in flush so that when we force a flush we make sure to flush all chunks.  I think this will make the medium-compact run consistently better performance.

The code is still doing unexpected things in medium-lsm-multi that impact performance.  The compacts do not fully merge with multiple tables and I haven't yet figured out why.
After talking with @agorrod and @michaelcahill I will remove the loop, but add a flushing state for compact that will be cleared when the flush completes by the worker thread.
