Fix unreachable internet for node groups created from launch template

[vradicevicds]

Current state of the terraform-aws-blueprints creates additional security groups for the cluster and nodes. These security groups are only applied to the node group if a node group has launch template. Such security group are not sufficient for SIMPHERA deployment.
This PR removes creation and attachment of mentioned security groups to enable SIMPHERA to work correctly.
Removal of security groups does not affect node's security. Such configuration is already manually used as a fix. Also, primary cluster security group is still present and is attached to created node groups.
