fix(api): fix GET /api serialization and webserver JFR event

[andrewazores]

Fixes #1191
Fixes #1192

• fix(api): GET /api returns properly serialized endpoint verb
• chore(log): replace request logging with Vertx impl
• correct event name and move into logging handler

Marked with backport label though I think it's too late to get this in to 2.2.0. These are lower-priority fixes solving problems that most users won't run into so if a 2.2.1 happens then this can get pulled in.

Everything looks good to me.

Should there be a test suite for RequestLoggingHandler?
For example testing the basic API specs, and that a WebServerRequest event is really emitted during a handling of some fake RequestHandler perhaps.

Actually... this would end up in the upstream 2.2.0 but it's too late for the downstream 2.2.0. Doesn't seem to make sense. I'll remove the label.
