multipath: Fix "COMPELNT"/"Compellent Vol" configuration
The multipath configuration we ship is missing important settings embedded in
multiapth daemon. Overriding these defaults is needed to enable vdsm required
configuration, but also remove any option we don't mention in our mulitpath
device configuration, causing possible reliability or performance issues.
The new configuration was copied from upstream multiapth-tools settings,
updated on 2013-07-16, and override the "features" and "no_path_retry" settings
required by vdsm.
Requires testing with the relevant storage server.
