New repo for advanced packaging tutorial (#9711)

* modified tutorial packages

* update hint in hdf5 tutorial file (typo for suggested argument)

* add repo.yaml to tutorial repository

* update tutorial docs to refer user to tutorial package repository

* flake edits

* recommend site scope vs. defaults

* you don't specify the repo's name when adding a repo, just the path

 Setup for the tutorial
 ----------------------
 
-The simplest way to follow along with this tutorial is to use our Docker image,
-which comes with Spack and various packages pre-installed:
+.. note::
 
-.. code-block:: console
-
-  $ docker pull alalazo/spack:advanced_packaging_tutorial
-  $ docker run --rm -h advanced-packaging-tutorial -it alalazo/spack:advanced_packaging_tutorial
-  root@advanced-packaging-tutorial:/#
-  root@advanced-packaging-tutorial:/# spack find
-  ==> 20 installed packages.
-  -- linux-ubuntu16.04-x86_64 / gcc@5.4.0 -------------------------
-  arpack-ng@3.5.0  hdf5@1.10.1   libpciaccess@0.13.5  libtool@2.4.6  m4@1.4.18  ncurses@6.0          openblas@0.2.20  openssl@1.0.2k     superlu@5.2.1       xz@5.2.3
-  cmake@3.9.4      hwloc@1.11.8  libsigsegv@2.11      libxml2@2.9.4  mpich@3.2  netlib-lapack@3.6.1  openmpi@3.0.0    pkg-config@0.29.2  util-macros@1.19.1  zlib@1.2.11
+  If you are not using the tutorial docker image, it is recommended that you
+  do this section of the tutorial in a fresh clone of Spack
 
-If you already started the image, you can set the ``EDITOR`` environment
-variable to your preferred editor (``vi``, ``emacs``, and ``nano`` are included in the image)
-and move directly to :ref:`adv_pkg_tutorial_start`.
-
-If you choose not to use the Docker image, you can clone the Spack repository
-and build the necessary bits yourself:
+The tutorial uses custom package definitions with missing sections that
+will be filled in during the tutorial. These package definitions are stored
+in a separate package repository, which can be enabled with:
 
 .. code-block:: console
 
-  $ git clone https://github.com/spack/spack.git
-  Cloning into 'spack'...
-  remote: Counting objects: 92731, done.
-  remote: Compressing objects: 100% (1108/1108), done.
-  remote: Total 92731 (delta 1964), reused 4186 (delta 1637), pack-reused 87932
-  Receiving objects: 100% (92731/92731), 33.31 MiB | 64.00 KiB/s, done.
-  Resolving deltas: 100% (43557/43557), done.
-  Checking connectivity... done.
-
-  $ cd spack
-  $ git checkout tutorials/advanced_packaging
-  Branch tutorials/advanced_packaging set up to track remote branch tutorials/advanced_packaging from origin.
-  Switched to a new branch 'tutorials/advanced_packaging'
-
-At this point you can install the software that will be used
-during the rest of the tutorial (the output of the commands is omitted
-for the sake of brevity):
+  $ spack repo add --scope=site var/spack/repos/tutorial
+
+If you are using the tutorial docker image, all dependency packages
+will have been installed. Otherwise, to install these packages you can use
+the following commands:
 
 .. code-block:: console
