Locust: Organize scripts to help with ease of use and maintenance.

[kcondon]

Current scripts structure:

1. Script to run eg. basic_test_04_mydata.py
   -contains task list of pages with weights
2. Separate creds.json file for input
   -contains user info
   -api keys
   -collection of random dataset ids as input to dataset task
3. Individual page scripts with additional input/ variables, eg. mydata_links.py

Suggested structure:

1. Utility page files that know how to call a particular page
2. Test files which contains a task list, uses the utility page files to execute tasks, accepts input from individual data files
3. Data files that allows specifying variable data such as persistent ids, usernames, etc.
4. Basic config file that specifies system under test (URL).
5. Test Suite file that calls set of test files?
