List installed build tools

I manage a bunch of jenkins servers with the client api, and I want to check what build tools are already installed on each installation.

How can I list the contents of ```https://jenkins-installation-hostname/configureTools/``` ?

```java
JenkinsServer jenkins = new JenkinsServer(..);

JenkinsBuildTools tools = jenkins.getBuildTools();
List jdks = tools.getJdks();
List mavens = tools.getMavens();

Map>> pluginNameToPluginDetails = tools.getRaw();
// "maven" -> [ ("version" -> "3.3.9", "installAutomatic" -> "true", "install from apache" -> "3.3.9", ...),
// ("version" -> "3.5.0", ..)]
// "java" -> [ ("version" -> "8u131", ..),
// ("version" -> "8u60", ..),
// ("version" -> "7u80", ..),
// ]
```
