Subject: [PATCH] Additional options for XenAPINFS cinder driver

Related to bp xenapi-storage-manager-nfs

Add configuration options to devstack scripts, so it is easier to set up
a system with a XenAPINFS volume backend. It makes possible to test this
configuration with exercises. To enable the XenAPINFS driver, specify:

CINDER_DRIVER=XenAPINFS
CINDER_XENAPI_CONNECTION_URL=<url for a xenserver>
CINDER_XENAPI_CONNECTION_USERNAME=<username for the xenserver>
CINDER_XENAPI_CONNECTION_PASSWORD=<password for the xenserver>
CINDER_XENAPI_NFS_SERVER=<a box that has an nfs export>
CINDER_XENAPI_NFS_SERVERPATH=<exported catalog>

in your localrc
