Plugins can no longer create new Metrics Categories

[jflo]

Steps to Reproduce (Bug)

1. Create a new plugin, which adds its own instance of MetricCategory to the MetricsCategoryRegistry service that is provided in the BesuContext at plugin registry time. Give it a unique name.
2. Deploy the plugin to any instance of Besu.
3. Startup the instance, with your new metrics category specified in the list of --metrics-categories to collect data on.

Expected behavior: new metrics are produced under the new category.

Actual behavior: Startup fails, because there is no MetricCategoryConverter for the string provided as an option to --metrics-categories. Plugin registration happens AFTER those converters are setup and used to parse the supplied --metrics-categories options.

Frequency: always

Logs (if a bug)

Please post relevant logs from Besu (and the consensus client, if running proof of stake) from before and after the issue.
