[blast] Add credentials-based K8s authentication for service users#7945
Conversation
Add K8sClient.from_credentials() as an alternative to kubeconfig-based auth. This allows external services to connect using AWS access keys and optionally assume an IAM role, without needing a kubeconfig file. - New CredentialsConfig dataclass for AWS credentials settings - from_credentials() classmethod generates EKS tokens via presigned STS URLs (same mechanism as `aws eks get-token`) - BLAST_FROM_CREDENTIALS=1 env var to enable in CLI, reads AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and optional BLAST_ROLE_ARN - Rate limiting (30 calls/60s) for credentials-based clients on write operations only (internal polling is not rate-limited) - _reload_client() auto-detects auth mode for token refresh
