Add logging capabilities

[NucciTheBoss]

Self explanatory - enable automatic logging for tests. This could involve "injectables" that copy stdout and stderr from the subprocess and save to a log file.

The question is whether or not this logging should be enabled by default? Personally, I would rather have the test be verbose and then allow end-users to pass a silent option through the test provider decorator. Another question is what should be captured in the log file? Information strictly about the testlet? What data is being loaded by cleantest? What arguments where passed to the hooks? The possibilities.

For now, let's keep it pretty simple.

Removed from 0.2.0 milestone due to time constraints and presentations.

I added logging capabilities to the LXDArchon class in the 0.5.0-dev branch so once those commits land I can finally close this issue after all these months 😅
