refactor(enricher): Cleanup up fabric8 specific enrichers

[rhuss]

Enrichers which are specific to the fabric8 platform (CD + UI) has been
moved into a "deprecated" enricher module. This can be kept as reference
or later easily removed. No enricher in this module is include in any
default profile and hence is disabled.

The enrichers that were disabled that way are:

• CdEnricher
• DocLinkEnricher
• GrafanaLinkEnricher
• IconEnricher

Some other refactoring consolidates on the naming of enrichers, so that
everything with a f8- prefix currently is about auto detection of
specific tech stacks (like specialized healthchecks or the prometheus
enricher)

All other are in the "standard" module and have a "fmp" prefix.

The MavenScmEnricher has been simplified a bit to remove duplicated SCM
information ("connection" and "developerConnection")

All integration tests have been adapted accordingly.

There is still one thing which I would like to improve in this PR: Currently in the "fabric8" enricher module, there are mostly healthcheck enrichers, one for each tech stack.

I'd like to move these health check enrichers to something more general like e.g. a "SpringBootEnricher" which is responsible for all Spring Boot specific enrichment (which currently is only for health checks). This would have the benefit to reduce the name of the enricher as it is also used in the configurtion to "spring-boot".

For this to work properly though, we should be able to allow nested configurtion from the very beginning so that a configuration for such an enricher could look like:

<enricher>
  <config>
    <spring-boot>
      <health>
         ...
      </health>
    </spring-boot>
  </config>

</enricher>

This could also map nicely to properties like it is done in the vertx-healtcheck enricher.

See also #1375 for this deep configuration aspect.

Of course, this probably would make sense for genertors, too.

Looks good, Thanks 👍

Shouldn't this be f8-healthcheck-vertx?
