Enable Account Activity in CloudGuard CSPM

**Describe the issue**
To onboard your CloudTrail for Intelligence analysis, select the S3 buckets that hold the logs. For centralized S3 buckets, you can select the accounts you want to analyze.
CloudGuard creates a CloudFormation template (CFT) to run in your AWS environment to handle the required configuration easier.
The process can take a few minutes to complete.
Important Prerequisites
Existing CloudTrail configured to store log files on an AWS S3 bucket.
The S3 bucket has to reside:
In the same AWS account with the CloudTrail.
In an AWS account onboarded to the same CloudGuard account as the logs account.
Note: In case of a trail for specific regions, only partial insights will be gained - for the full value, each account should have a multi-region trail.
Note:
CloudGuard does not fix, edit, or delete existing bucket's event notifications or SNS topic policies.
CFT and Accounts steps are skipped in some onboarding scenarios.
