features:
- |
Add new role parameters `NovaCPUAllocationRatio`, `NovaRAMAllocationRatio`
and `NovaDiskAllocationRatio` which allows to configure `cpu_allocation_ratio`,
`ram_allocation_ratio` and `disk_allocation_ratio`.
Default value for NovaCPUAllocationRatio is 0.0
Default value for NovaRAMAllocationRatio is 1.0
Default value for NovaDiskAllocationRatio is 0.0
The default values for CPU and Disk allocation ratio
are taken 0.0 as mentioned in [1].
