{cmd,}/k8s-operator: support IRSA for Recorder resources (#15913)

Adds Recorder fields to configure the name and annotations of the ServiceAccount
created for and used by its associated StatefulSet. This allows the created Pod
to authenticate with AWS without requiring a Secret with static credentials,
using AWS' IAM Roles for Service Accounts feature, documented here:
https://docs.aws.amazon.com/eks/latest/userguide/iam-roles-for-service-accounts.html

Fixes #15875
