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 'use.local.storage' to set the zone level config for local storage.
(cherry picked from commit 62710aed37606168012a0ed255a876c8e7954010)

Review: https://reviews.apache.org/r/6733/
Testing: Applied patch, and ran 'ant clean-all build-apidocs'
on both OSX and Ubuntu 12. Initial testing confirmed the issue
that Greg discovered on OSX. After the patch, the docs built
correctly.
Support for up to 16 VDIs per VM on XS 6.0 and above (16 VDIs => root + cd + 14 data volumes). Currently in CS number of data disk that can be attached to VM is hard-coded to 6. Made this setting configurable by moving it to hypervisor capabilities. Although XS 6.0 and above supports upto 16 VDIs but while testing on XS 6.0.2 found that only 13 data volumes can be attached to a VM. So for XS 6.0 and 6.0.2 max_data_volumes_limit is set to 13 currently.
