  ENH: configurable XINFERENCE_HOME
  ### Is your feature request related to a problem? Please describe
  XINFERENCE_HOME should be configurable.
  
  ### Describe the solution you'd like
  We could starts with supporting the XINFERENCE_HOME env variable. This could be done by adding an util `get_xinference_home` and make sure this is the only way to get xinference home.
