docs: reorganize local guides in tutorials There is too much information in each of the local/k8s/dev docs pages. The "guides" that are listed in each one of those pages are moved either to "common tasks" or to a dedicated "tutorials" section. This paves the way for more comprehensive tutorials, where we describe how to run the latest master branches of Open edX. I am well aware that, as they stand, the tutorials are of poor quality and should be rewritten. This is a task for another day/commit. For now, we only move the contents to a separate part of the docs. Also, we should add a "reference" section to the docs, where we add the result of `tutor <subcommand> --help`.

Making backups and migrating data
---------------------------------
With Tutor, all data are stored in a single folder. This means that it's extremely easy to migrate an existing platform to a different server. For instance, it's possible to configure a platform locally on a laptop, and then move this platform to a production server.
1. Make sure `tutor` is installed on both servers with the same version.
2. Stop any running platform on server 1::
tutor local stop
minor typos fixed

3. Transfer the configuration, environment, and platform data from server 1 to server 2::

Fix command to Transfer the configuration, environment, and platform data from server 1 to server 2 I added `rsync` to Transfer the configuration, environment, and platform data from server 1 to server 2 command so that we can we able to transfer data. I found that `-avr` options fit well to it.

4. On server 2, move the data to the right location::
mv /tmp/tutor "$(tutor config printroot)"
5. Start the instance with::
tutor local start -d
Making database dumps
---------------------
To dump all data from the MySQL and Mongodb databases used on the platform, run the following commands::
docs: specify root username in mysql dump instructions The default user in the mysql container is 'mysql', so the `mysql` command tries to use the 'mysql' MySQL user by default. But, in the MySQL dump instructions, we are providing the MySQL root user's password, so we need to specify `MYSQL_ROOT_USERNAME` as the MySQL user when invoking `mysql`.

tutor local exec \
-e USERNAME="$(tutor config printvalue MYSQL_ROOT_USERNAME)" \
-e PASSWORD="$(tutor config printvalue MYSQL_ROOT_PASSWORD)" \
mysql sh -c 'mysqldump --all-databases --user=$USERNAME --password=$PASSWORD > /var/lib/mysql/dump.sql'

tutor local exec mongodb mongodump --out=/data/db/dump.mongodb
The ``dump.sql`` and ``dump.mongodb`` files will be located in ``$(tutor config printroot)/data/mysql`` and ``$(tutor config printroot)/data/mongodb``.
