Parse plugin configuration tags

[lucasoares]

Currently, the plugin configuration is not parsed.

Example:

      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <configuration>
          <skip>true</skip>
        </configuration>
      </plugin>
    </plugins>

The current gopom implementation doesn't let you get configurations for a plugin.

You are correct, we are currently not parsing the configuration even though we should.

Feel free to create a PR with the fix. Unfortunately I will not have time to fix this myself for a couple of weeks.

The fix for this is now available in version v0.2.2 thanks to @akadir
