CLOUDSTACK-5028. Vmware instance fails to start when the chain_info of any volume that belongs to the VM is longer than 255 characters.
If the VM has snapshots then the chain_info of a volume can be longer than 255 characters.
Increasing the column length of chain_info in VolumeVO to match the maximum length of type text(db schema type)
fixing simulator for missing haplanners
CLOUDSTACK-3715. Socket timeout error is observed in VMware setup if a VMware task (RelocateVM_Task, CloneVM_Task etc.) takes more than 10 minutes. Making this value configurable to allow admins to modify the timeout if required. It defaults to the current value i.e. 10 minutes.
multiEdit: extend field hide/show functionality

-Support passing isHidden option as closure, for conditional hide/show
 based on context

-Adds new option format for isHidden option:

return false == show field and all columns (default)
return true == hide only header and form column
return 2 == hide header and form, as well as returned item column -- these
item columns will be skipped over entirely, not just hidden

CLOUDSTACK-5038:
used cpu is getting bumped up when the over provisioning factor > 1. This was because we didnt record the overprovisioning factors of the vms which got deployed pre 4.2
Upgrade path will fix that by populating the cpu/mem overprovisioning factors for each of the vms in user_vm_details table using the global overprovisioning factor.

CLOUDSTACK-5061 - Cloudstack doesn't consider storage overprovisioning factor when using thin Provisioning over VMWare VMFS datastores

Fix is use the storage overprovisioning factor (global configuration parameter "storage.overprovisioning.factor") to calculate total provisioning capacity for storage space allocation over VMFS based storage pools as well.
There are two level of thin provisioning provided in VMware, storage level and file-level (VMDK) thin provisioning. in CloudStack, all volumes are provisioned with thin VMDK format, so at hypervisor level, we ALWAYS do thin provisioning. If storage vendor has the ability to provide storage level thin provisioning in addition to VMDK thin provisioning, it is also allowed since it is transparent to Cloudstack.
