feat(client): Teach option flag for tracing requests

[deis-admin]

An option flag to trace requests would help users understand how communication between the client and the server occur, as well as help understand where a connection issue may occur, such as in a proxied environment or if DNS routes are set up incorrectly.

Common client option flags would be --debug, --verbose or --trace. I'm personally in favour of --verbose as typically you can tune the verbosity up or down based on your needs.

Copied from original issue: deis/deis#2884

@bacongobbler What would this output look like? Things that could be shown with --verbose:

• [ ] request URL
• [ ] request body
• [ ] response body/headers
