  1. config-linux: add schemata field to IntelRdt

    Add a new "schemata" field to the Linux IntelRdt configuration. This
    addresses the complexity of separate schema fields and resolves the
    issue of supporting currently uncovered RDT features like L2 cache
    allocation and CDP (Code and Data Prioritization).
    
    The new field is for specifying the complete schemata (all schemas) to
    be written to the schemata file in Linux resctrl fs. The aim is for
    simple usage and runtime implementation (by not requiring any
    parsing/filtering of data or otherwise re-implement parsing or
    validation of the Linux resctrl interface) and also to support all RDT
    features now and in the future (i.e. schemas like L2, L2CODE, L2DATA,
    L3CODE and L3DATA and who knows L4 or something else in the future).
    
    Behavior of existing fields is not changed but it is required that the
    new schemata field is applied last.
