Convert all HTML doc to RST

The motivation for this conversion is to have DevStack's docs be
generated using a more familair workflow for OpenStack projects, using
Sphinx.

Changing from raw HTML to RST will also make it easier to contribute
more documentation, as well as making edits less of a hassle.

The majority of the work was done by using Pandoc to convert from HTML
to RST, with minor edits to the output to remove errors in Sphinx.

+eucarc EC2 settings
+-------------------
+
+``eucarc`` creates EC2 credentials for the current user as defined by
+``OS_TENANT_NAME:OS_USERNAME``. ``eucarc`` sources ``openrc`` at the
+beginning (which in turn sources ``stackrc`` and ``localrc``) in order
+to set credentials to create EC2 credentials in Keystone.
+
+EC2\_URL
+    Set the EC2 url for euca2ools. The endpoint is extracted from the
+    service catalog for ``OS_TENANT_NAME:OS_USERNAME``.
+
+    ::
+
+        EC2_URL=$(keystone catalog --service ec2 | awk '/ publicURL / { print $4 }')
+
+S3\_URL
+    Set the S3 endpoint for euca2ools. The endpoint is extracted from
+    the service catalog for ``OS_TENANT_NAME:OS_USERNAME``.
+
+    ::
+
+        export S3_URL=$(keystone catalog --service s3 | awk '/ publicURL / { print $4 }')
+
+EC2\_ACCESS\_KEY, EC2\_SECRET\_KEY
+    Create EC2 credentials for the current tenant:user in Keystone.
+
+    ::
+
+        CREDS=$(keystone ec2-credentials-create)
+        export EC2_ACCESS_KEY=$(echo "$CREDS" | awk '/ access / { print $4 }')
+        export EC2_SECRET_KEY=$(echo "$CREDS" | awk '/ secret / { print $4 }')
+
+Certificates for Bundling
+    Euca2ools requires certificate files to enable bundle uploading. The
+    exercise script ``exercises/bundle.sh`` demonstrated retrieving
+    certificates using the Nova CLI.
+
+    ::
+
+        EC2_PRIVATE_KEY=pk.pem
+        EC2_CERT=cert.pem
+        NOVA_CERT=cacert.pem
+        EUCALYPTUS_CERT=${NOVA_CERT}
