Rename trace types

[coot]

All trace types should follow the following naming convention Trace<NAME>. Furthermore, all traces configurable by cardano-node should use the same type name as the corresponding option.

This will simplify the process of finding the right option to enable a given tracer or finding the trace type corresponding to a given option.

Please be aware that with the new tracing system these options disappear. Maybe you want to defer this change to a point after new-tracing has become the new standard?

[coot]

@jutaro the new tracing system is probably also using some kind of filtering of messages by tracer name, isn't it? If so is this derived from trace type name?

[jutaro]

Yes, it uses hierarchical names as you can see here: https://github.com/input-output-hk/cardano-node/blob/master/doc/new-tracing/tracers_doc_generated.md
