Display custom list of controllers when adding virtual disk to VM

Author: @Xavier Thevenot

To override the hypervisor plugin's list of controllers (and controller types) for when users assign a virtual disk to a VM, add the following property in client-config-custom.json file.

{
    [...],
    "config.harddiskcustomcontrollertypes" : ["TYPE1", "TYPE2"]
    "config.harddiskcustomcontrollers" : ["CUSTOMCONTROLLER1", "CUSTOMCONTROLLER2"]
}

Combo boxes will display this custom list of controllers (and controller types). If you do not set the property, Abiquo will display all controllers. If you specify only one value, this value will be automatically assigned (forced).
