Support simplified allocation schema in config
Support simplified allocation schema in config

Make it possible to specify allocation schema without the "all" key.

That is, e.g. instead of:
  <partition>:
    l3Allocation:
      all: 90%
    mbAllocation:
      all: [100%]

  <class>:
    l3schema:
      all: 0x1f
    mbschema:
      all: [100MBps, 50%]

one can simply specify:
  <partition>:
    l3Allocation: 90%
    mbAllocation: [100%]

  <class>:
    l3schema: 0x1f
    mbschema: [100MBps, 50%]

Makes configuration easier/cleaner in the common use case where no
per-cacheId allocations are specified.
