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"

instead of

docker-bench/cfg/cis-1.3.1/definitions.yaml

Line 1313 in b6e798b

- flag: "Memory"

Other affected checks

docker-bench/cfg/cis-1.3.1/definitions.yaml

Line 1333 in b6e798b

- id: 5.11

is also affected, possibly more checks are affected.
