Add a simple templating system to Baserock definitionssam/easy-templating

This is currently independent of the actual definitions format. The
'configure' tool generates actual .morph files from .morph.in files,
and build tools then operate on these generated .morph files.t

This is largely untested and no doubt broken!

+description: |
+  This is an example cluster morphology for deploying a Trove,
+  both the initial deployment and an upgrade.
+
+  You need some ssh keys, which you can create like this:
+
+      mkdir ssh_keys
+      ssh-keygen -N '' -f ssh_keys/lorry.key
+      ssh-keygen -N '' -f ssh_keys/worker.key
+      ssh-keygen -N '' -f ssh_keys/trove-admin.key
+
+  You may also put in your own keys instead of creating new ones.
+
+  To do the initial deployment:
+
+      morph deploy clusters/trove-example.morph \
+          initial \
+          initial.location=kvm+ssh://liw@192.168.122.1/test-trove/tmp/test-trove.img
+
+  To do an upgrade:
+
+      morph deploy clusters/trove-example.morph \
+          upgrade upgrade.VERSION_LABEL=123
+
+  where `VERSION_LABEL` gets a new unique value each time.
+
+  Remember to always specify either initial or upgrade as the
+  deployment name to use, otherwise morph will attempt to deploy both.
+
+  You can find documentation for Trove at the following web address:
