Subject: add tutorial setup script to share/spack (#17705)

* add tutorial setup script to share/spack

* Add check for Ubuntu 18, fix xvda check, fix apt-get errors
  - now works on t2.micro, t2.small, and m instances
  - apt-get needs retries around it to work

+#
+# This file is part of Spack and sets up the environment for the Spack tutorial
+# It is intended to be run on ubuntu-18.04 or an ubuntu-18.04 container or AWS
+# cloud9 environment
+#
+# Components:
+# 1. apt installs for packages used in the tutorial
+#     these include compilers and externals used by the tutorial and
+#     basic spack requirements like python and curl
+# 2. spack configuration files
+#     these set the default configuration for Spack to use x86_64 and suppress
+#     certain gpg warnings. The gpg warnings are not relevant for the tutorial
+#     and the default x86_64 architecture allows us to run the same tutorial on
+#     any x86_64 architecture without needing new binary packages.
+# 3. aws cloud9 configuration to expand available storage
+#     when we run on aws cloud9 we have to expand the storage from 10G to 30G
+#     because we install too much software for a default cloud9 instance
