Mark Stemm 4cfb58f675 Limit the number of reported items
In some evironments, there may be a very large number of images,
containers, etc not satisfying a given test. For example, in one
environment, we saw *378k* images not satisfying 4.6, mostly because
the customer was never cleaning up old images.

To avoid overly long lists of items, add a new option "-n LIMIT" that
limits the number of items included in JSON output. When the limit is
reached, the list will be truncated and a trailing (truncated) will be
added. Here's an example:

```
{"id": "5.9", "desc": "Ensure the host's network namespace is not
shared", "result": "WARN", "details": "Containers running with
networking mode 'host':  k8s_POD_storage-provisioner_kube-system_ef960ef5-62c5-11e9-802f-08002719228f_0
k8s_POD_kube-proxy-xfln8_kube-system_ee70c4c3-62c5-11e9-802f-08002719228f_0 (truncated)",
"items":
["k8s_POD_storage-provisioner_kube-system_ef960ef5-62c5-11e9-802f-08002719228f_0","k8s_POD_kube-proxy-xfln8_kube-system_ee70c4c3-62c5-11e9-802f-08002719228f_0","(truncated)"]},
```
