Similar to how the react panels make sure all data is SeriesData before passing it to the react panels, this makes sure SeriesData is converted to TableData|TimeSeries before passing it to the angular panels.

It also changes the typing to encourage using SeriesData for future development

Since we do not like some of the default golint rules,
this commit proposes to use https://github.com/mgechev/revive.

And potential revive speed-up should't hurt :).

Right now, presented config (./conf/revive.toml) is permissive,
we might improve it over time however. Fixes for found revive
issues in the code are very limited so it wouldn't be large to review.

Also in this commit:

* Add annotations for makefile commands and declare phony targets

* Rename "gometalinter" script and CI command to "lint"
  since we are doing there a bit more then using gometalinter package

* Add Makefile rules to .editorconfig

* Documentation which mentioned "golint" replaced with revive
