Enable rspec documentation formatter and color output

Current rspec just outputs a = as each test runs. This enables the documentation formatter and color output to make it easier to know what is going on with each spec.

Wouldn't it be better to enable it in .rspec, which would also make it possible to use documentation formatter in development environment?

This will also make build logs to be massive, which may not work good on slower machines, but it is probably reasonable move

Right now the Fuubar output format is used for the dev environment. I think not everyone wants the documentation output when they run rspec in the dev environment. In the CI builds, it makes more sense because the progress bar is not very helpful.

Also, any ideas why color outputting isn't being shown here? Is ANSI support required?

[Grzegorz Bizon]

@stanhu I would guess that this is ANSI terminal issue, which would be hopefully resolved by https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/5744
