(core) Add flexibility to daily API usage limit

Summary: Allow exceeding the daily API usage limit for a doc based on additional allocations for the current hour and minute. See the doc comment on getDocApiUsageKeysToIncr for details. This means that up to 5 redis keys may be relevant at a time for a single document.

Test Plan: Updated and expanded 'Daily API Limit' tests.
