cis-1.3.1: 5.10 and 5.11 (possibly more checks) don't work properly

# Observation

The problem seems to be due to the format of the output returned by the audit command, which contains the container Id.
For example

```
docker ps --quiet --all | xargs docker inspect --format '{{ .Id }}:Memory={{ .HostConfig.Memory }}'
87d3272a4a42fdeb534935bccb9b934f13761fc7e8ba82e233de581213d05359:Memory=268435456
```

is considered a `FAIL` by

```
docker run --memory=256m hello-world:latest
sudo docker-bench --benchmark cis-1.3.1 --include-test-output --config-dir /etc/docker-bench/cfg | grep "] 5.10" -A 1
```

```
[FAIL] 5.10 Ensure that the memory usage for container is limited (Automated)

```

# Possible solution

It seems like the problem can be resolved by using a regex

```
tests:
test_items:
- flag: ".*Memory"
```

docker-bench https://github.com/aquasecurity/docker-bench/releases/tag/v0.5.0 `docker-bench_0.5.0_linux_amd64.rpm`

Start in cfg/cis-1.3.1/definitions.yaml around the referenced lines 1313 and 1333, and run the provided docker-bench command with --benchmark cis-1.3.1 and --include-test-output. Compare the checks' handling of output prefixed by a container ID; done means checks 5.10, 5.11, and any similarly affected checks correctly evaluate the Docker output.
