Deprecate environment as an argument for dbconsole and console

People should rather rely on the `-e` or `--environment` options to
specify in which environment they want to work. This will allow us
to specify the connection to pick as a regular argument in the future.

+*   Passing the environment's name as a regular argument to the
+    `rails dbconsole` and `rails console` commands is deprecated.
+    The `-e` option should be used instead.
+
+    Previously:

+    Now:
+
+        $ bin/rails dbconsole -e production

 *   Allow to pass a custom connection name to the `rails dbconsole`
     command when using a 3-level database configuration.
