Only show group member roles if explicitly requested

This very simply fixes an EE problem, but I made the change here so it's less prone to errors from merges.

In EE, prior to this change, group member roles were shown in project member list when a project is shared with a group. This is bad because the project explicitly shares with the group and sets a 'max access' level. If the max access level is 'developer' the project owner doesn't want to see 'Owner' in the group roles because it will confuse them. I verified that permissions are really being honored here, it was just an error in the view. You can see in https://gitlab.com/gitlab-org/gitlab-ee/blob/master/app/views/projects/project_members/_shared_group_members.html.haml#L18 where this was how it was intended to be. Likely a CE-EE merge introduced this bug. That's why I made the boolean required in CE even though this is for EE.

Fix help keyboard shortcut for relative URL setups

Fixes gitlab-org/gitlab-ce#12751

See merge request !3016

Fix relative URL

See https://github.com/gitlabhq/gitlabhq/issues/10053

 1. Same configuration way for relative URL like with Omnibus
 2. Loading the relative configuration from Rakefile as Rails do not load initializers for `asset:precompile`

First point has another positive side effect: no collisions (due to git controlled `application.rb`) any more during the upgrades of source based installations and relative url configuration

 - [x] tests on the source based installation
 - [x] tests on the centos&ubuntu omnibus packages

Fixes: gitlab-org/gitlab-ce#13730, gitlab-org/gitlab-ce#13727, gitlab-org/omnibus-gitlab#1143 and https://github.com/gitlabhq/gitlabhq/issues/10053

Don't show any "2FA required" message if it's not actually required

Prior, if the user had enabled and then disabled 2FA, they would be
shown a "You must enable Two-factor Authentication for your account."
message when going back to re-activate it, even if 2FA enforcement was
disabled.

Branded appearance to CE

Closes #11489

The difference with the EE version is only that there is no distinction between light and dark logos, though this wasn't used anyway. If this is fine, I'll create a MR on EE too.

TODO:
- [x] Copy docs
- [x] Make new screenshots
- [ ] Remove Custom Welcome message feature?

@rymai: I was unsure what labels to add to ping you, so I just ping you like this 😉

Move "I should see Crowd login form" feature to a view spec

We were doing all kinds of code gymnastics to "enable" Crowd in the
feature spec and this would sometimes cause a transient failure.

Really what it's testing is if the Crowd login form shows when Crowd's
enabled, so this is much better suited to a view spec.
