This improvement should improve usability of sentry performance

This PR consists of two changes:

  1. Removed http method from transaction name (this is unnecessary because sentry performance has http method info already)
  2. Changed transaction name to context.FullPath() witch is more readable for endpoint owners

Changes are shown in screenshot. First one is before, second one is after

Can you confirm all routes will now be fully parameterized?

If yes, you can update sentry.WithTransactionSource(sentry.SourceURL) to sentry.WithTransactionSource(sentry.SourceRoute).

@antonsacred No, all good. CI failed because our Windows tests started to be a bit flaky. We'll get this merged in the next few days.

For not found routes returns an empty string.

This causes issues for 404 routes, as the transaction name is now always something like GET .
We should check for the return of c.FullPath(). If it's empty, use c.Request.URL.Path as a fallback and set sentry.WithTransactionSource(sentry.SourceURL).

@antonsacred I think what @cleptric suggests is more like, do the check and fallback here in handle directly (not in defer), and set TransactionSource depending on the value of c.FullPath().

@tonyo thanks for the take. I like your proposal. I have changed the code.

It would be great to test different paths, like /panic, /panic/:id etc.
