Add possibility to provide own github url (#2)

- Add possibility to provide own github url
- Add before-commit script, fix vendor, fix formatting
- Fix the ValidOwner checker:
  problem was that in `validateTeam` function we used GetName() instead of GetSlug(). Slug is normalized team name which is always used in codeowners file, e.g. team name **Technical Writers** is normalized to **technical-writers** and such name is used in codeowners file.
- Remove the GolangCI integration
