Add basic Makefile

There are a couple of targets in here that some might find useful in
doing DevStack testing in multiple remote VMs.

There are some of the usual boring targets too, like stack and unstack,
that do exactly what you would expect.

+#             DS_REMOTE_URL must be set on the command line
+#
+# ds-push - Merge a list of branches taken from .ds-test and push them
+#           to the ds-remote repo in ds-test branch
+#
+# ds-pull - Pull the remote ds-test branch into a fresh local branch

+
+# Duplicated from stackrc for now

+# while keeping the working repo local.

+# It requires:
+# * a remote pointing to a remote repo, often GitHub is used for this
+# * a branch name to be used on the remote
+# * a local file containing the list of local branches to be merged into
+#   the remote branch
