This patches provide qmp interface to query/set io throttle parameters of a fsdev.
Some of patches also refactor the code and structure that was present in block and fsdev files.

  fsdev-throttle-qmp: factor out throttle code to reuse code
  fsdev-throttle-qmp: Rename the ThrottleLimits member names
  fsdev-throttle-qmp: Rewrite BlockIOThrottle with ThrottleLimits as its
    base class
  fsdev-throttle-qmp: Move ThrottleLimits into a new file for future
    reuse
