Introduce a switch if imported dependencies should also be analysed

[PeterWippermann]

In my application I use Spring Boot. Thus I set up the Dependency Management as follows:

        <dependencyManagement>
          <dependencies>
            <!-- Spring Cloud Dependencies -->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud-dependencies.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

Sprint Boot will manage my dependencies for me and guarantees that the selected versions work well together.
That's why I'd like to exclude the dependencies that are imported by Spring Boot from the versions:dependency-updates-report report. Otherwise I get suggested updates in my report that are out of scope for me.

I think it would be great to introduce a new boolean parameter to toogle if those imported dependencies should also be analysed. To stay backwards compatible it would default to true.

Don't get me wrong: I still want the importing dependency to be analysed, but not the dependencies it imports. That way I would still get notified if there's a newer version of Spring Boot / Dependencies.

I think this has already been raised in #46

It depends, I still want <dependencyManagement> to be processed so I get notified about outdated versions. However, I don't want to be informed about transitive and/or imported dependencies.

In #46 the OP asked to totally disable processing of dep-mgmt on request.

Currently the result of this looks like this:

What do you think?

Hi @khmarbaise ,
your solution looks great to me! Thanks for incorporating this feature and mainting this project :-)
On my behalf, sorry for the late feedback...

I'd be very happy to use it in my current setup! Is there a chance for a 2.5 release in the near future? I saw you usually release once a year or less.
