Check network predictor DB size

Project Member Reported by mariakho...@chromium.org, Jun 21 2016

Issue description

Predictor loads the entire prediction database into memory.  Unclear how large that can be - the size of this database decays based on age, not on total database size.

Measure the size of this in production and/or consider other more aggressive schemes for reducing the size of this database under memory pressure.

csharrison has already started investigating this.
Right, we are planning on capping the size by moving to a MRU style database with a fixed element count.
Status: Fixed (was: Assigned)
Marking this as fixed. We capped the size to 100 elements, which should give us a upper bound of 1100 hosts. We also have UMA measuring size.
