Added builtin performance metrics. Add REPORT=true to one of your disco dance runs to print the report at the end, or use 'disco report' to produce a report on the last disco dance; reports are cleared at the beginning of every disco dance.

_internal diff is for the time taken to produce the filesystem diff
_internal fetch_params is for how long it took to fetch all the client parameters

Currently these performance numbers only account for about 50-70% of disco's activity, not sure how to report on the rest yet.

Example output:
