Shows quotaSummary in API documentation

[RodrigoDLopez]

Description

Through analysis, it was found that the Cloudstack API documentation (https://cloudstack.apache.org/api/apidocs-4.17) does not present the document for the quotaSummary API. This error has been present since the creation of this API.
The present patch corrects this behavior, exposing the documentation for this API to the user.

How Has This Been Tested?

To generate the documentation and verify the correction, you can run mvn clean install inside the tools/apidoc project and check the content of the page present in tools/apidoc/target/xmldoc/html/index.html. Or run the build-apidoc.sh script:

`./build-apidoc.sh 4.17.0.0 ../../client/target//cloud-client-ui-4.17.0.0.jar ../../client/target//cloud-client-ui-4.17.00.jar ./myout

and check the page content available in myout/xmldoc/html/index.html

@DaanHoogland I did mess with the other PR. I closed that one and opened this one with the asked target.
