It can be expensive to compute these metrics. In particular, when
retrieveing the amount of jumbo chunks, an index is not being used and
consequently the query triggers an expensive COLLSCAN. For big
databases, this query has negative impact on the cluster performance.
in this commit:
- centralize logging output handler.
- set global Info/Debug/Error log levels based on config file or flags.
- remove per-plugin debug arg handling.
- add a I!, D!, or E! to every log message.
- add configuration option to specify where to send logs.

a bit nicer. And make it easier for contributors to lookup the few data
types that they actually care about.
