[Bug 1496210] Re: multipath-tools lacks the default settings for IBM 2810XIV storage system

[Mathieu Trudel-Lapierre]

Is this change really needed on 15.10? It seems to me like we're already
carrying the proper options for 2810XIV given that the only elements
missing from the hw table are setting configuration options to their
default values anyway?

Bug description:
  ---Problem Description---
  multipath-tools is lacking the settings for IBM 2810XIV storage system

  Specially, the lack of queue_if_no_path is problematic on PowerVM LPM (live partition migration) operations, 
  because I/O errors will trigger filesystem errors, which on ext4 remount the fs in read-only mode, by default.

  Please incorporate this upstream commit in 15.10, 15.04 and 14.04:
      864162b08067d3e55d52996846d10a046956c6d6 Add default values for IBM XIV Storage System.

  ---uname output---
  Ubuntu 15.10, 15.04, and 14.04
   
  ---Additional Hardware Info---
  IBM 2810XIV Storage 

  The upstream commit applies cleanly on 15.10 (0.5.0-based) and 15.04,
  14.04 (0.4.9-based).
