Pass principal name as part of aws subscoped credentials session name #3196
Description
Is your feature request related to a problem? Please describe.
We are trying to monitor how different principals use the catalog. While Polaris listeners enable us to audit table reads on table level, we also need information regarding physical storage reads for each principal, for example to keep track of the s3 costs incurred by each. This seems to be impossible at the moment when using vended credentials as all subscoped credentials are produced by the same parent role and session name for each subscoped credential is a simple hardcoded value - "PolarisAwsCredentialsStorageIntegration".
Describe the solution you'd like
It would be ideal to use principal name as part of the session name so that the final value would look something like this "Polaris_TestPrincipal" (probably best to keep the prefix short as session name length is capped at 64 chars). This would enable users to use aws monitoring tools like CloudTrail to get better information about physical s3 reads.
