Address comments from Shane: 

1. At log parsing time, pass Lustre striping information to DXLT module
  a. Obtain Lustre striping information in Lustre Module.
  b. Cache file striping information and map it to file name.
  c. Pass file striping information to DXLT module for each file.

2. In DXLT module, print Lustre striping and OST information if file system type is Lustre.
