commands: consume DEBUG environment variable

Browse Source 
When running in standalone mode, the --debug flag passed to docker
cannot be passed. The docker cli also supports a DEBUG env var, however,
in standalone mode this won't be consumed.

This patch reads the contents of the DEBUG environment variable, and
enables debugging logs when it's been set.
