This method existed to allow LDAP users to take over existing GitLab
accounts if the part before the '@' of their LDAP email attribute
matched the username of an existing GitLab user. I propose to disable
this behavior in order to prevent unintended GitLab account takeovers.

After this change it is still possible to take over an existing GitLab
account with your LDAP credentials, as long as the GitLab account email
address matches the LDAP user email address.

The example LDAP configuration in gitlab.yml enables the
allow_username_or_email_login setting. Because the effect of this
setting is somewhat counterintuitive, I propose we make 'false' the
example default. The settings initializer already sets this setting to
'false'.

Before this change we were trying to configure Rails.cache in an
initializer. It seems that by the time the initializers are loaded,
Rails.cache is already instantiated, so changing the settings does not
achieve anything anymore. This was causing Rails to default to a file
storage cache instead of the Redis cache, which in turn broke `rake
cache:clear`.
