Support for cciss disks (HP Smart Array)

Instead of
  /dev/hda        with /dev/hda1, they have
  /dev/cciss/c0d0 with /dev/cciss/c0d0p1

and ohai reports them as "cciss!c0d0"

Switch to using the Disk management from the Barclamp library

This, among other things allows to use cinder and swift
storage on the same node, and also opens the way for future code
cleanup.
Remove disk_enum_expr and disk_test_expr

Both attributes are now entirely unused.
Detach devices that do not have a matching UUID anymore

Otherwise applying the barclamp fails after replacing harddrives
(or when reapplying a newly created proposal).
Ignore mount errors on boot

If an (old) Swift device cannot be mounted anymore, ignore
that and let chef-client clean it up.
Disable container and JSON report by default

Only the Crowbar UI uses the JSON output, so enabling it
by default can break other scripts.

Replication of containers is very CPU intensive, and creating
2560 for "reporting" is a bit too much overhead by default.
Set log_facility for keystonauth middleware

Otherwise, unconfigured keystoneclient logging triggers annoying
syslog messages:

$ swift --insecure list

Message from syslogd@d52-54-00-26-22-3a at Sep 13 13:47:02 ...
 <131>proxy-server STDOUT: No handlers could be found for logger
 "keystoneclient.common.cms" (txn: txe68451518fc146169ef57b4ee4d83fa5)
Remove trailing white space
Fix logical thinko in host comparison

node[:fqdn]!=t[:fqdn] always matches, because t is a string (of IP
address), and node[:fqdn] is a hostname.
