New object model for Agents endpoint

[ehrnst]

Current agent endpoint is almost useless. Properties are missing and raw data is outputted without any meta data

[latens]

What kind of meta data are you missing?

[ehrnst]

We will have to create a model for the output. Right now, theres only raw data.
So ID and name are just listed out. There would be better to output like this
{
id: ,
name: ,
[...]
}
