[WIP] Replace Godep with Glide

Closed Tomasz Maczukin requested to merge replace-godep-with-glide into master

What does this MR do?

Replaces Godep with Glide (https://github.com/Masterminds/glide) as the dependencies manager used by this project.

Why was this MR needed?

Godep is sometimes tricky to use. Glide seems to be easier to use and more prepared to use with /vendor directory.

Does this MR meet the acceptance criteria?

  • CHANGELOG entry added
  • Documentation created/updated
  • Tests
    • Added for this feature/bug
    • All builds are passing
  • Branch has no merge conflicts with master (if you do - rebase it please)
