Issue #, if available:
https://github.com/aws/eks-anywhere-internal/issues/2650
#9177

Description of changes:
As part of migrating from using long term credentials in e2e test, I am making changes here to use session token and propogate it to secrets which will be used by curated packages.

Testing (if applicable):
Created a cluster and verified that secrets created has the session token if available. Tested the normal case where there is no session token
