volumetype functionality

[alessandroargentieri]

Some regions are flagged with the custom_storage_class: true:

$ curl -H "Authorization: Bearer `mycivoapikey`" https://api.civo.com/v2/regions | jq
[
  {
    "code": "<regionCode>",
    "name": "<regionName>",
    ...
    "features": {
         ... 
         "custom_storage_class": true
    },
  },

For these regions we would like to add the new command:

civo volumetypes ls

This will wrap a HTTP call returning a JSON array of elements like:

GET /v2/volumetypes
Response:
[
   {
     "name": "ms-xfs-2-replicas"
     "description": "<OPTIONAL>",
     "flags": ["foo", "bar"] // OPTIONAL
   },
   {
      "name": "ms-xfs-3-replicas"
      "description": "<OPTIONAL>",
      "flags": ["foo", "bar"] // OPTIONAL
    },
]

The user can select a volumetype.name and pass to the following:

civo instance create myinstance --volume-type=<VOLUMETYPENAME_HERE>
civo volume create myvolume --volume-type=<VOLUMETYPENAME_HERE>

The civo instance show <INSTANCE_NAME> and the civo volume show <VOLUME_NAME> will show the VolumeType if it comes in the response (optional).

N.B. It needs a new civogo tag @fulviodenza can you provide it?

@alessandroargentieri Sure, I will do as soon as the PR civo/civogo#209 is merged
