softlayer_file_storage requires a different IOPS value than what is stored in state

[lgfa29]

When ordering a softlayer_file_storage resource you need to specify a value for iops which can be 0.25, 2, 4 or 10.

But after the resource is created, the value stored in the Terraform state has more decimals, so, for example,4 is stored as 4.096 and 10 is stored as 10.24.

This causes a subsequent terraform plan to incorrect flag the resource as needing to be recreated.

Steps to reproduce

1. Order a softlayer_file_storage:

resource "softlayer_file_storage" "nfs" {
    type = "Endurance"
    datacenter = "tor01"
    capacity = 500
    iops = 4
}

2. terraform apply
3. terraform plan gives wrong result:

/+ softlayer_file_storage.nfs
    capacity:                           "500" => "500"
    datacenter:                         "tor01" => "tor01"
    hostname:                           "[OMITTED]" => "<computed>"
    iops:                               "4.096" => "4" (forces new resource)
    snapshot_capacity:                  "500" => "500"
    type:                               "Endurance" => "Endurance"
    volumename:                         "[OMITTED]" => "<computed>"

Expected result

No changes required

Environment

Terraform v0.8.8
terraform-provider-softlayer v1.4.0
