Investigate the need for TestContextSetting

[kgress]

Summary

The TestContextSetting interface contains a collection of constant values that are currently being used along with the BaseTestContext singleton for adding and getting settings to the WebDriverContext.

Over half of these are not being used:

• PROXY_MANAGER
• PROXY_ASSIGNER
• QUEUE_HOST
• QUEUE_NAME
• TEST_APPLICATION_CONTEXT

We should take a look and see if these values are required. Even further, we should determine if the TestContextSetting is necessary at all.

A/C

• Investigate whether or not the TestContextSetting interface is required
• After determination, commit changes and submit PR if a code change is required
