cinder nfs share require additional files to be deployed

[Lingfeng Xiong]

If configure cinder with NFS, it is required to deploy a file like "nfsshare.txt" to target's /etc/ . Currently it seems no support for such deployment because kolla only allows modify and merge configuration files, not adding one.

    Allow cinder-volume to be configured to use NFS

    Allow cinder-volume, nova-compute and nova-libvirtd to be configured to
    use NFS. In order to mount and work with NFS shares, several containers
    needed the NFS packages installed during build time.

    One somewhat significant change is the addition of an explicit bind
    volume for nova-compute that has shared mounts enabled.

    According to docker-run(1), the shared mount propagation flag can only
    be specified for bind mounted Docker volumes and not named volumes.

    In an NFS setup, cinder-volume mounts the NFS shares so that it can
    create and manage the Cinder volumes. When a new instance is created
    with a Cinder volume or a Cinder volume is attached to an existing
    instance, nova-compute mounts the Cinder volume from the NFS share for
    nova-libvirtd. In order for nova-libvirtd to then see those Cinder
    volumes the shared mounts flag must be enabled for the Docker volume.

    Remove the rpcbind container as it is only necessary for operators who
    are using NFSv3 or lower. There is no known need for this currently
    however, this container can be added in the future should an operator
    require it.
