conan-center hooks 'final report'

[ericriff]

Having the conan-center hook activated is super useful to find common errors / tidy up your code, but under some circumstances it is extremely chatty which makes easy to miss an error / warning since they fly by so quickly and get buried under a million lines of log.

I don't know if this is possible but I would like to have a 'final report' in my console after a conan create execution that tells me if the hook detected errors or not (and even better list the errors).

Another thing would be to make the hook display only warnings and errors, and not the 'OK' lines.

Thanks!

Conan-center hooks uses output.success which a regular message output. Conan uses it a lot, se we can't set a global log level. What we could is adding an env var to filter it.

It can be related to conan-io/conan#8570. We provide a final report, we would need a post command hook. For now, we can't provide a final report, as depending which conan command we run, it will or not execute a step.

What we do now, is silencing INFO and printing only WARNING and ERROR.
