logging

[davidegraff]

Describe the problem
TDC currently prints a bunch of status messages to standard out. This presents a few problems for the client:

• clutters my terminal
• it's impossible to selectively turn them off
• it's non-trivial to save them alongside other logging messages if I want to inspect them at a later date

Describe the solution you'd like
Move most logging statements from print_sys calls to logger.* calls

I.e., at the top of most modules:

import logging

logger = logging.getLogger(__name__)

# print_sys(mesg)
logger.*(mesg)

where * is the appropriate method depending on the severity of the message (debug, info, warn, error, critical)

Additional context
this page contains some good resources for addressing this
