added properties filters on interopgui.properties

add to ```~/.m2/settings.xml```

```
<profile>
      <id>testing-hub</id>
          <properties>
              <truststore.path>/tmp/hub/truststore.jks</truststore.path>
              <privkeypem.path>/tmp/hub/cakey-nopass.pem</privkeypem.path>
              <cacertpem.path>/tmp/hub/cacert.pem</cacertpem.path>
          </properties>
    </profile>

```

so when you ```jetty:run```  you can pass in the profile with the correct locations

```mvn clean package jetty:run -Ptesting-hub```
