Optimize record filtering by start and end date

Registered by Ilya Shakhat

There are many places in dashboard where records are filtered by date:
 * Module contribution report
 * Timeline
 * Openstack.org members report
 * Filters for KPI reports
 * Man-day metric
All these requests require iterating over all records. Instead an index should be introduced into memory_storage and records should be filtered by indexes.
