Merge branch 'email_in_gravatar_urls' of gitlab.com:arnaud/gitlab-ce into email_in_gravatar_urls
Give the Rails cache its own Redis namespace

Before this change, Rails cache data was stored in a global Redis
namespace. As a consequence, clearing the Rails cache (`rake
cache:clear`) would also delete all Sidekiq queue data and session
storage. This change puts all Rails cache data in a `cache:gitlab`
namespace, making `rake cache:clear` safe again.

 Merge branch 'email_in_gravatar_urls' into 'master'

allow passing user's email address in custom Gravatar urls

Some custom avatar systems use the user's email address rather than its hash. This merge request will allow the administrator to configure gitlab-ce to use the user's email address gravatar.plain_url and  gravatar.ssl_url in the config file like this:

```
gravatar:
    enabled: true
    plain_url: "http://company.com/avatar/?mail=%{email}&size=%{size}"
    ssl_url: "https://company.com/avatar/?mail=%{email}&size=%{size}"
```

It's a only a 2 word patch.
