add jwt reflect and resource config to support jwt authentication type

[atomfrede]

Native image can be build with jwt support and started. I got some errors when I tried to save a user (entity) but I seemed unrelated. Will open another issue for that.

@alina-yur especially for you

closes #48

Looks like the threadpool for sending mails async is not working properly (non webflux). Going to investigate today. Besides that it looks quite well.

[atomfrede]

Very strange, after I disabled async mail sending, the thymeleaf template can't be compile, because of an error with org.thymeleaf.exceptions.TemplateProcessingException: Exception evaluating SpringEL expression: "locale.language". Which is confusing as we have the same template with webflux and I can see there is a locale (which has of course a public getLanguage method).

Seems I found a solution. Let me update the PR

@mraible There seems to be an issue with macos ci. Will restart the failed builds, but everything works fine, now also with JWT 🎉

macOS docker install is flaky. It should be ok to merge on install failures.
Samples are ok now, should be ok to merge if succeed.

[atomfrede]

I have fixed remaining issues with webflux and reflect config. Macos build is working fine locally, so as @mshima said flaky environment. I would say let's merge it and create a new release.
