[FEA] Scale: Support huge number of eventlogs in single qualification process run

[tgravescs]

Is your feature request related to a problem? Please describe.
There are different aspects to scaling. Here we want to be able to run a single instance of the qualification tool on a single machine and have it be able to process 100,000+ event logs. The main issue here is that we keep all the application summary information in memory until we do the final output. There are a couple of solutions to this:

1. output the information for each application as soon as we are done processing it
2. Store the application summary on disk in like a database rather then memory.

This issue is going to focus on number 2 and store the information in Rocks DB
