epriestley 5b463e634c Write fewer "applied" rows and clean up excess historical rows
Summary:
  - Only write the <ruleID, phid> row if the rule is a one-time rule.
  - Delete all the rows for rules which aren't one-time.

NOTE: This is probably like several million rows for Facebook and could take a
while.

Test Plan:
Added some one-time and every-time rules, ran them against objects, verified
only relevant rows were inserted.
Ran upgrade script against a database with one-time and every-time "ruleapplied"
rows, got the irrelevant rows removed.
