RFC: Add -verbose option

[msmith-techempower]

Summary

Debugging something locally right now requires building a local verifier, commenting out the pull command (to cause it to use the local), and comment out (usually) the stdout/err stripping functionality from the loggers to get full logging for toolset/verifier debugging. Adding a -verbose flag to pass to the verifier and use in the toolset would allow a quick way to turn on WAY MORE information that we have available and currently just throw away.

For example, a verification run could easily spit out all the headers and the body of the request with the verbose flag present.
