sdong f1b9f804e9 Add a mode to always pick the oldest file to compact for each level 
Summary:
Add options.compaction_pri, which specifies the policy about which file to compact first.
kCompactionPriByLargestSeq will compact oldest files first.
Verified the behavior in db_bench but did not write unit tests yet. Also need to make it settable through option string and dynamically changeable.

Test Plan: Will write unit tests
