Add release procedure

[jmesnil]

@radcortez I'm adding release procedure to components that are used in WildFly to reduce our bus factor :)

Could you please have a look and check that I got the release procedure right?
FIY, I did the same thing for smallrye/jandex#446

thanks!

Hey @jmesnil how are you? :)

We have the process documented here:
https://github.com/smallrye/smallrye/wiki/Release-Process

Maybe we just need to link from it? Let me know if all the required information is there.

@radcortez Hey, thanks for the link. I was not able to find it so there's value to link it directly from the README :)

I've amended my PR to link to it.

As a side note, there is a lot of good info in the https://github.com/smallrye/smallrye repo but it's not easy to find. Maybe we could pin it from https://github.com/smallrye or use a .github repository to highlight it?

Definitely. I'll do that. Thanks!
