Ashlesha Atrey f6dcd44f21 Implement logging for mixer
Implement the logging package for mixer.

A common log file can be set for all the mixer commands in the
builder.conf. E.g. `mixer config set Mixer.LOG <filepath>`

The log file and level can also be set for individual mixer
commands using the `--log` and `--log-level` flags respectively.

The various log levels are:
ERROR (1), WARNING (2), INFO (3), DEBUG (4) and VERBOSE (5).
Default log level is 4.

Fixes #666
