Unified linter job

[carpawell]

Is your feature request related to a problem? Please describe.

One GO repo -- one linter job. Many repos -- many jobs. One change -- many PRs in every repo. Many repos -- one (almost) GO team with the same (almost) ways to write code.

Describe the solution you'd like

Find out if it is possible to unify the linter action (and its settings).

Describe alternatives you've considered

Do nothing.

Additional context

DCO work done once: #12, #15.
