epriestley 99cbc20778 Reduce the verbosity of the "Aphlict" log
Summary:
See PHI1692. Currently, the Aphlict log is ridiculously verbose. As an initial pass at improving this:

  - When starting in "debug" mode, pass "--debug=1" to Node.
  - In Node, separate logging into "log" (lower-volume, more-important messages) and "trace" (higher-volume, less-important messages).
  - Only print "trace" messages in "debug" mode.

Test Plan: Ran Aphlict in debug and non-debug modes. Behavior unchanged in debug mode, but log has more sensible verbosity in non-debug mode.
