Rule for ADA-CP 2.11.1 "Eliminate use of the 'root' user for administrative and daily tasks"

[rdegraaf]

Is your feature request related to a problem? Please describe.

The App Defense Alliance Cloud Profile requires a check that AWS root account credentials have not been used recently. This is closely related to the existing rule "iam-root-account-used-recently" except that both ADA-CP 1.0 and CIS 2.0 apply to API keys in addition to passwords.

Describe the solution you'd like

Implement the check as documented at https://github.com/appdefensealliance/ASA-WG/blob/v1.0/Cloud%20App%20and%20Config%20Profile/Cloud%20App%20and%20Config%20Test%20Guide.md#2111-eliminate-use-of-the-root-user-for-administrative-and-daily-tasks.
