  - Do not use bindmounts for nfs tests

    This commit removes bindmounting
    of host directories to containers in play-resources tests.
    It seems that it is unneeded, and it is enough to just create anonymous volumes
    instead of cluttering host filesystem.
    This is one part of a preparation for removing the cleanup-directories
    role that won't be needed anymore.
    Note: similar changes were made to the nfs
    role tests, for the same reasons, but
    cleanup-directories is not used there
