Filter and display instance storage information

[stefansundin]

Would be cool if you could filter by type of instance storage (HDD/SSD/NVME) and amount of storage, i.e. --instance-storage-type, --instance-storage-min and --instance-storage-max. And then have the instance storage information displayed in the output.

If I get the time later then I might make an attempt at implementing this myself.

Relevant info from aws-sdk-go:

https://docs.aws.amazon.com/sdk-for-go/api/service/ec2/#DescribeInstanceTypesInput

    //    * instance-storage-info.disk.count - The number of local disks.
    //
    //    * instance-storage-info.disk.size-in-gb - The storage size of each instance
    //    storage disk, in GB.
    //
    //    * instance-storage-info.disk.type - The storage technology for the local
    //    instance storage disks (hdd | ssd).
    //
    //    * instance-storage-info.nvme-support - Indicates whether non-volatile
    //    memory express (NVMe) is supported for instance store (required | supported)
    //    | unsupported).
    //
    //    * instance-storage-info.total-size-in-gb - The total amount of storage
    //    available from all local instance storage, in GB.
    //
    //    * instance-storage-supported - Indicates whether the instance type has
    //    local instance storage (true | false).

https://docs.aws.amazon.com/sdk-for-go/api/service/ec2/#InstanceTypeInfo

    // Describes the instance storage for the instance type.
    InstanceStorageInfo *InstanceStorageInfo `locationName:"instanceStorageInfo" type:"structure"`

    // Indicates whether instance storage is supported.
    InstanceStorageSupported *bool `locationName:"instanceStorageSupported" type:"boolean"`
