Allow to render node names with templates

[dgolovin]

Every kind of node should have default template. There should be preference that allows to modify default template per node kind.

@dgolovin could you provide more detail on this?

It is just an idea to allow users to define rendering for TreeItem labels. Every TreeItem is based on json data. Currently we just hardcode labels in tree for different node kinds. I was thinking to have preference where you can define template for any node kind using strings like "#{refrernce.to.json.attriburte} static text". Then tree data provider would use that string to generate label for specific node and replace #{} to real value from json data.

It is totally optional feature.
