Chore: Implement revive (#16200)

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

Fixes #16109
Ref #16160
