This fixes a bug where wiki repositories for projects with an empty main
repository would not get backed up.

Fixes a bug with non-UTF8 locales introduced by
2b816075.

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.

This fixes issue #161.

On GitLab Cloud, MySQL connection reaping seemed to cause more problems
(exceptions and segfaults in the native MySQL client) than it solved.

The Satellite#create method no longer sets the `$?` global variable.
Instead, we can use the method return value to test if the satellite was
created successfully

Before there was a bug in omniauth-ldap which prevented samaccountname
showing up as a possible username for new LDAP users. Thanks to upstream
fixes, we no longer need to work around this bug.

Invoking 'db:schema:load' turned out to be a bad idea: when downgrading
an existing GitLab installation, the schema of the newer version would
be preserved when trying to import the old version.
