Steps to reproduce the issue:
(1)Create 10000 service offerings (by db changes below or cloudmonkey).
```
DROP PROCEDURE IF EXISTS cloud.insert_service_offering;
DELIMITER $$
CREATE PROCEDURE cloud.insert_service_offering()
BEGIN
DECLARE count INT DEFAULT 10000;
SET @offeringid = (select max(id)+1 from disk_offering);
WHILE count > 0 DO
INSERT INTO disk_offering (id,name,uuid,display_text,disk_size,type,created) values (@offeringid,'test-offering-wei',uuid(), 'test-offering-wei',0,'Service',now());
INSERT INTO service_offering (id,cpu,speed,ram_size) values (@offeringid, 1, 500,256);
SET @offeringid = @offeringid + 1;
SET count = count - 1;
END WHILE;
END $$
DELIMITER ;
CALL cloud.insert_service_offering();
mysql> CALL cloud.insert_service_offering();
Query OK, 0 rows affected (2 min 30.85 sec)
```
(2) Check the total time of periodical capacity check in cloudstack.
Without this patch, it spend 2.5 seconds (2 hosts)
```

With this patch ,it spend 1.3 seconds (2 hosts)

```
If there are 100 hosts, the total time will be reduced from 100+ seconds to around 10 seconds.
This feature enables the following:
Balanced migration of data objects from source Image store to destination Image store(s)
Complete migration of data
setting an image store to read-only
viewing download progress of templates across all data stores
Related Primate PR: apache/cloudstack-primate#326
This PR adds minor version support when mounting nfs on the SSVM as requested in #2861
The global setting "secstorage.nfs.version" has been changed to use the String data type which allows any minor version to be specified.
While migrate a vm, in the popup, the host dedicated to other accounts/domains are also 'Suitable" for migration, which is obviously wrong.
The same issue happens with api findHostsForMigration
Currently in cloudstack, when we click on "Acquire New Ip", it will
randomly acquire IP from the pool. With this enhancement, it is
possible to select the IP from the drop down IP list of that network.
Same thing applies for a VPC as well.

Feature Specification: https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=95653548
Live storage migration on KVM under these conditions:
From source and destination hosts within the same cluster
From NFS primary storage to NFS cluster-wide primary storage
Source NFS and destination NFS storage mounted on hosts
In order to enable this functionality, database should be updated in order to enable live storage capacibilty for KVM, if previous conditions are met. This is due to existing conflicts between qemu and libvirt versions. This has been tested on CentOS 6 hosts.
Additional notes:
To use this feature set the storage_motion_supported=1 in the hypervisor_capability table for KVM. This is done by default as the feature may not work in some environments, read below.
This feature of online storage+VM migration for KVM will only work with CentOS6 and possible Ubuntu as KVM hosts but not with CentOS7 due to:
https://bugs.centos.org/view.php?id=14026https://bugzilla.redhat.com/show_bug.cgi?id=1219541
On CentOS7 the error we see is: " error: unable to execute QEMU command 'migrate': this feature or command is not currently supported" (reference https://ask.openstack.org/en/question/94186/live-migration-unable-to-execute-qemu-command-migrate/). Reading through various lists looks like the migrate feature with qemu may be available with paid versions of RHEL-EV but not centos7 however this works with CentOS6.
Fix for CentOS 7:
Create repo file on /etc/yum.repos.d/:
[qemu-kvm-rhev]
name=oVirt rebuilds of qemu-kvm-rhev
baseurl=http://resources.ovirt.org/pub/ovirt-3.5/rpm/el7Server/
mirrorlist=http://resources.ovirt.org/pub/yum-repo/mirrorlist-ovirt-3.5-el7Server
enabled=1
skip_if_unavailable=1
gpgcheck=0
yum install qemu-kvm-common-ev-2.3.0-29.1.el7.x86_64 qemu-kvm-ev-2.3.0-29.1.el7.x86_64 qemu-img-ev-2.3.0-29.1.el7.x86_64
Reboot host

Allows creating storage offerings associated with particular domain(s) and zone(s). In create disk/storage offfering form UI, a mult-select control has been addded to select desired zone(s) and domain select element has been made multi-select.
createDiskOffering API has been modified to allow passing list of domain and zone IDs with keys domainids and zoneids respectively. These lists are stored in DB in cloud.disk_offering_details table with 'domainids' and 'zoneids' key as string of comma separated list of IDs. Response for create, update and list disk offering APIs will return domainids, domainnames, zoneids and zonenames in details object of offering.
listDiskOfferings API has been modified to allow passing zoneid to return only offerings which are associated with the zone.
