Move verbosity configuration to the API

[dodie]

Currently the verbose logs can be activated with the scottDebug environment variable. This is not flexible, as clients of the instrumentation API (other than Scott Test Reporter) might want to enable this.

Goal:

• Change the logging to be toggled with a parameter in the new Configuration API instead of an environment variable.
• Update Scott Test Report's agent and API based instrumentation to appropriately set this parameter when it encounters the scottDebug environment variable.
