Review request for cloudstack, Abhinandan Prateek and Nitin Mehta.


Support for local data disk. Currently enable/disable config is at zone level, in subsequent
checkins it can be made more granular.
    Following changes are made:
    - Create disk offering API now takes an extra parameter to denote storage type (local
or shared). This is similar to storage type in service offering.
    - Create/delete of data volume on local storage
    - Attach/detach for local data volumes. Re-attach is allowed as long as vm host and data
volume storage pool host is same.
    - Migration of VM instance is not supported if it uses local root or data volumes.
    - Migrate is not supported for local volumes.
    - Zone level config to enable/disable local storage usage for service and disk offerings.
    - Local storage gets discovered when a host is added/reconnected if zone level config
is enabled. When disabled existing local storages are not removed but any new local storage
is not added.
    - Deploy VM command validates service and disk offerings based on local storage config.
    - Upgrade uses the global config '' to set the zone level config for
local storage.
