Autodetect regions

[devt]

Use case
In a large org with many accounts optional regions are enabled only in several dozens accounts and we don't necessarily have a list, If we run for all optional regions, we get lots of errors (several hundreds of accounts report 4-5 errors about regions not being present)

Auto detect what regions to scan
Would like the code to operate in all regions which are enabled for the specific account

Additional context
Above implies we make a call to ec2.describe_regions for each account and this is what determines which regions are scanned

Thanks for opening this feature request. We have added this to our backlog and will review in the next release planning.

We reviewed this issue and will be supporting this feature request. However, we will implement list_regions API call using 'account' client instead of describe_regions using 'ec2' client.

The prefer to use list_regions API because it allows us to provide RegionOptStatusContains=['ENABLED'|'ENABLED_BY_DEFAULT']
