f314df12c3 Refactor: use lazy logging
As described in pep282 [1], the variable part of a log message
should be passed in via parameter.  In this case the parameters
are evaluated only when they need to be.

This patch fixes (unifies) this for DIB.

A check using pylint was added that this kind of passing parameters to
the logging subsystem is enforced in future.  As a blueprint a similar
(stripped-down) approach from cinder [2] was used.

b9c065de28 Remove args from BlockDevice() init
The args agument was only used to find the symbol for the getval
command.  Have the command pass the symbol to find in directly.  We
can therefore remove the args paramater to the BlockDevice() creation.

c74ba2fe74 Move to subparsers
Move argument parsing to subparsers, rather than positional arguments.
This better reflects the tool's role as a driver and allows
sub-commands to deal with arguments in a natural way.

ff5b30db8a Create BlockDeviceCmd object
This creates a BlockDeviceCmd object to hold the main() function.
This doesn't really do anything different right now, but sets a base
for using argparse subparsers to handle the command-line

a06c610a8c Move YAML parsing into cmd.py; default to env
This moves the YAML parameter parsing into the command-line driver.
It makes the argument optional so it can be taken from the environment
variable directly.  The parsed YAML is passed to the BlockDevice
object.
