Performance benchmark for catalog application

[sandbergja]

Requirements:

• This benchmark should be for the application as a whole, not just one component (e.g. solr)
• This benchmark should be run in the staging environment
• We document how to run this benchmark and store the results
• This should include considerations of increasing numbers of users and requests. Note if there is a threshold where performance decreases significantly.
• Important parts of the application to test: A keyword search, An advanced search, A show page, Loading a requests form

A nice tool to consider that @acozine brought it to my attention https://github.com/JoeDog/siege brew install siege (for local dev testing)
