Make the eniconfig name as string in the template.

When an ENIConfig with name is given a number, instead of string,

apiVersion: crd.k8s.amazonaws.com/v1alpha1
kind: ENIConfig
metadata:
    name: 3
    namespace: kube-system
spec:
    securityGroups:
        - sg-xx
        - sg-xx2
    subnet: subnet-xxx

the helm chart apply throws an error stating

unable to ssa object &{Object:map ... } ... name is required

We have to make the eniconfig name as string in the template.
