fix(scheduler): show more information when there is a HTTP error in Kubernetes

[helgi]

With the response below the user would get the very unhelpful 422 Invalid - This extends that

{
    'code': 422,
    'reason': 'Invalid',
    'apiVersion': 'v1',
    'metadata': {},
    'kind': 'Status',
    'details': {
        'kind': 'Service',
        'causes': [
            {'field': 'spec.clusterIP', 'reason': 'FieldValueInvalid', 'message': "invalid value '', Details: range is full"}
        ],
        'name': 'test-760092409'
    },
    'message': 'Service "test-760092409" is invalid: spec.clusterIP: invalid value \'\', Details: range is full',
    'status': 'Failure'
}
