Debugging the agent is a huge pain point. Tracebacks are rarely logged, error messages are often only returned via the API, and lack of info logging makes it hard to determine where some failures occur. Some errors only return a 500 with no error message or logs. Change-Id: I0a127de6e4abf62e20d5c5ad583ba46738604d2d
