Marc Jay 5bab65c56d - Remove securityhub output mode and replace with '-S' flag to send findings to Security Hub
- Move Security Hub related code to a dedicated include/securityhub_integration file
- Check that Security Hub is enabled in the target region before beginning checks when -S is specified
- Add error handling to the batch-import-findings call
- Add CHECK_ASFF_TYPE variables to all CIS checks to override the default
- Add support for CHECK_ASFF_RESOURCE_TYPE variables which override the default 'AwsAccount' value for the resource a finding relates to.
- Add CHECK_ASFF_RESOURCE_TYPE variables to all checks where there is a suitable value in the schema
- Remove json-asff output for info messages as they are not appropriate for possible submission to Security Hub
- Update the README to cover Security Hub integration
- Add an IAM policy JSON document that provides the necessary BatchImportFindings permission for Security Hub
- Remove trailing whitespace and periods in pass/fail messages to be consistent with the majority of messages, to prevent future tidy-up from changing the finding IDs
