vgroup does not support `pending_only`

[sanderdescamps]

At the moment it is not possible to query for the deleted volume groups. The GetVgroup method does not support any params. Therefore it is not possible to add the option pending_only=true. Also the vgroup struct does not have support for the response.

Is this something that could be added?

GET vgroup?pending_only=true

curl -k -XGET "${PURE_URL}/api/${PURE_API_VERSION}/vgroup?pending_only=true" \
    -H 'Content-Type: application/json' \
    -b cookies.txt | jq -r '.'

[
  {
    "time_remaining": 85656,
    "name": "test",
    "volumes": []
  }
]

GET vgroup/{vgroup}?pending_only=true

curl -k -XGET "${PURE_URL}/api/${PURE_API_VERSION}/vgroup/test?pending_only=true" \
    -H 'Content-Type: application/json' \
    -b cookies.txt | jq -r '.'

{
  "time_remaining": 84816,
  "name": "test",
  "volumes": []
}
