Re: [libvirt] [PATCH v2 2/6] nfs: Add infrastructure to manage XML namespace options

Introduce the virStoragePoolNetFSMountOptionsDef to be used to manage the NFS Storage Pool XML Namespace for mount options. Using a new virStorageBackendNamespaceInit function, set the virStoragePoolXMLNamespace into the _virStoragePoolOptions when the storage backend is loaded.
