Previous boottool versions logged every single command that was run,
but that was considered to be exceedingly verbose, because all of those
commands and output/return would show in *.DEBUG files. Now, when running
into bugs, we frequently have add log statements to the _run_* methods.
This patch checks an environment variable and logs debug messages if
it is set. I chose to keep that as an extra knob, as casual users
may want to see debug messages ('--verbose=5') but not every single
command run and it's output/return code.
