feat: add possibiblity to use AWS IAM roles for service accounts

[ghost]

what

• To allow usage of AWS IRSA the assume role policy of the created IAM role needs to be adapted, therefore an additional (and optional) statement for the sts:AssumeRoleWithWebIdentity action was added
• To decouple sts:AssumeRole for the Service and the AWS principal types all statements have been split into separate blocks

why

• To allow usage of AWS IAM roles inside of EKS AWS
• more secure than handling AWS access keys and secrets
