Storage feature for virtual and hardware servers

Should be something like this page:
https://cloud.ibm.com/gen1/infrastructure/virtual-server/62941551/details#storage
https://cloud.ibm.com/gen1/infrastructure/bare-metal/943379/details#storage

List out all the storage the host has access to
- ISCSI
- Block
- Local
- Portable Storage ( for VSI )


command should be `slcli vs storage <VSID>`
