Add go.d documentation and modify collector menu (#5215)

docs/generator/buildyaml.sh
* Modified menu structure of collectors
* Added go.d plugin

docs/generator/buildhtml.sh
* Added go.d documentation (git clone). Clean up the go.d cloned dir before and after execution
* Replace page edit links to github for go.d.plugin. Removed nomkdocs option which doesn't work with this.
