fix: make refinery run from minimal config

[kentquirk]

Which problem is this PR solving?

• All the config changes had some minor issues that kept refinery from starting up with minimal configuration. This fixes that.

Short description of the changes

• logrus -> stdout
• fix sequencing of metrics startup
• fix default peer for file-based peer list
• add UnmarshalText method to log level
• the injection system was randomly starting up the transmissions before the metrics object, which shouldn't have been possible. I couldn't figure out why it was happening, so we now call start on transmissions manually after everything else.

@kentquirk looks like there might be a bad rebase in here
