Virtual Machine Remote Snapshot Usage

HyperCloud adds a new tag to the VM monitoring data returned by the orchestrator API calls one.vm.monitoring and one.vm.info. This tag is called HYPERCLOUD_REMOTE_SNAPUSAGE. It contains base64-encoded zlib-compressed JSON. Example data:

<VM>
    <MONITORING>
        <HYPERCLOUD_REMOTE_SNAPUSAGE>
            <![CDATA[eJzFjb0KwjAUhfc+xp0buElsEt1E3IoublJKwGADtilNU9CSdzeLzkoFt8P5+2YYTOtGU/tO975xYx28vhrYnLMZbJukT3qGTrfJhHJ72O3L44lQwglCDq9ZynQYHZkYaVwYbnfCkCFKTukKkfBU7Qc3WW9dZy61t490x3AtaZFqOQT/dqkUVKAUKuaLuMWXXMWVEriUKv5Clb+nfnqFsYpZFZ8rXK/G]]>
        </HYPERCLOUD_REMOTE_SNAPUSAGE>
    </MONITORING>
</VM>

Which is then parsed into:

[lancelot] root@hypercloud-dashboard:~# hypercloud vm show 3 | grep HYPERCLOUD_REMOTE_SNAPUSAGE | awk '{print $NF}' | base64 -d | openssl zlib -d
{
   "remote_snapshot_usage" : [
      {
         "images" : [
            {

               "provisioned_size" : 209715200,
               "used_size" : 176160768,
               "snapshot" : "auto-v2-hourly-202007311400-3"
            },
            {
               "provisioned_size" : 209715200,
               "name" : "LANCELOT-1-3-0",

               "used_size" : 8388608
            },
            {
               "name" : "LANCELOT-1-3-0",
               "provisioned_size" : 209715200,
               "used_size" : 8388608,
               "snapshot" : "auto-v2-hourly-202007311600-3"
            },
            {
               "name" : "LANCELOT-1-3-0",
               "provisioned_size" : 209715200,
               "used_size" : 8388608,
               "snapshot" : "auto-v2-hourly-202007311700-3"
            },
            {
               "provisioned_size" : 209715200,
               "name" : "LANCELOT-1-3-0",
               "used_size" : 0
            }
         ]
      }
   ]
}
[lancelot] root@hypercloud-dashboard:~# 

Which indicates that there are four remote snapshots plus the base image volumes with their respective usage information. The images are from the source HyperCloud cluster named LANCELOT.
