Implement Credential Cache for AWS Roles to reduce AWS API calls

[ThaSami]

Proposal

In the current KEDA versions, each use of the AWS_ROLE_ARN in triggerAuthentication results in a new request for credentials, even if multiple ScaledObjects use the same AWS role or the same TriggerAuth. To enhance efficiency and reduce redundant AWS calls, I propose implementing a credential cache mechanism. This cache would store credentials for AWS roles, allowing subsequent requests by different ScaledObjects to access these cached credentials instead of repeatedly querying AWS.
