Current implementation requires server pools to have same erasure stripe sizes, to facilitate same SLA and expectations. This PR allows server pools to be variadic, i.e they do not have to be same erasure stripe sizes - instead they should have SLA for parity ratio. If the parity ratio cannot be guaranteed by the new server pool, the deployment is rejected i.e server pool expansion is not allowed.
