The subdomain elevator we were using, which is included in apartment, didn't work on hosts already including a subdomain (like demo.consul.dev, for instance). In those cases, we would manually add the subdomain to the list of excluded subdomains. Since these subdomains will be different for different CONSUL installations, it meant each installation had to customize the code. Furthermore, existing installations using subdomains would stop working. So we're using a custom method to find the current tenant, based on the host defined in `default_url_options`. In order to avoid any side-effects on single-tenant applications, we're adding a new configuration option to enable multitenancy We're enabling two ways to handle this configuration option: a) Change the application_custom.rb file, which is under version control b) Change the secrets.yml file, which is not under version control This way people prefering to handle configuration options through version control can do so, while people who prefer handling configuration options through te secrets.yml file can do so as well. We're also disabling the super-annoying warnings mentioning there are no tenants which we got every time we run migrations on single-tenant applications. These messages will only be enabled when the multitenancy feature is enabled too. For this reason, we're also disabling the multitenancy feature in the development environment by default.
