Remove site:run goal in order to reduce amount of dependencies

[kwin]

New feature, improvement proposal

The mojo https://github.com/apache/maven-site-plugin/blob/master/src/main/java/org/apache/maven/plugins/site/run/SiteRunMojo.java depends on Jetty. However in most cases the site doesn't need to be served via a web server but can be used directly from the filesystem with a browser.

Update:
Currently there is on demand-rendering (hot-reload) implemented via https://github.com/apache/maven-site-plugin/blob/master/src/main/java/org/apache/maven/plugins/site/run/DoxiaFilter.java. Maybe instead implementing a hot-reload just based on filesystem monitoring should be used.

I like this idea, but removing a goal does break our public interface in a major way. I'm not sure how widely used this goal is. I wonder if it would ake sense to make this a deprecated alias for site:site?

site:site is quite different from my perspective therefore as first step I would just deprecate without making it an alias.
