Allow for Organization created trails

[0xdabbad00]

Normal CloudTrail logs are stored in:

s3://my_log_bucket/OPTIONAL_PREFIX/AWSLogs/111111111111/CloudTrail/

Organization CloudTrail logs are stored in:

s3://my_log_bucket/OPTIONAL_PREFIX/AWSLogs/o-ORGANIZATION_ID/111111111111/CloudTrail/

I need to account for that o-ORGANIZATION_ID sub-directory.

One method may be to have in the config.yaml the full path to the CloudTrail logs, such as:

accounts:
  - name: demo
    id: 111111111111
    iam: account-data/demo_iam.json
    cloudtrail_logs: s3://my_log_bucket/OPTIONAL_PREFIX/AWSLogs/o-ORGANIZATION_ID/111111111111/CloudTrail/
