When looking up a user by DN, use single scope

Fixes 500 error when user types in wrong group name.

Run tests in parallel on travis

The blocked? method is used to check whether a user exists in LDAP. Prior to this change, if the LDAP server had more objects below the one pointed to by the DN, those objects would also be picked up by the search, causing the method to determine the user should be blocked.

One case where this can happen is when using Active Directory and a user have a mobile phone assigned. In this case, Exchange will add an entry called ExchangeActiveSyncDevices under the users entry. The user-visible behaviour is then that a user loses Gitlab access when he enables a mobile device.

This fix sets the search scope to BaseObject in order to ensure that only the user itself is returned.

Respect the configured redis URL when initializing the session store

It was not possible to start Gitlab with a redis server running on another host or port. Every other subsystem that uses redis respects the settings in config/resque.yml.

This patch uses the configured url from the cache_store configuration.
The cache_store configuration already loads the correct redis url from config/resque.yml.

Closes #5406

Check if a file is editied "on" a branch or a commit.

The previous behavior was a "disabled" link, which was still clickable
and linked to the edit file action.

If the 	user accesses a path like "/edit/master/README" show the file
edit form (just like before).

If the user accesses a path like
"/edit/8d5c1f375ce99e5df84e26b0eafbf1448c6a001e/README", redirect the
user to the file detail page with a note, that he cannot edit a file
"on" a commit.

fixes #5482
