Create Swift directory d1 if needed

Swift added a requirement that storage directories must exist before
using them. In case of the d1 directory in TripleO - used when there are
no "real disks" - it has to be created by TripleO in advance.

+    Swift added a requirement to ensure that storage directories exist before
+    using them. However, when local directories are used in Tripleo (storing
+    data in /srv/node/d1), these are missing by default and thus Swift won't
+    store any data. This fix creates this directory if needed.
