make addon argocd application names lower case

[csantanapr]

In all addons argocd app follow the pattern to specify the name using cluster name, but the cluster name can have upper case letters like using EKS cluster name "Carlos Cluster" we need to lower case and replace space with dash -

For example in https://github.com/gitops-bridge-dev/gitops-bridge-argocd-control-plane-template/blob/main/bootstrap/control-plane/addons/aws/addons-aws-load-balancer-controller-appset.yaml#L41

  template:
    metadata:
      name: addon-{{name}}-{{values.addonChart}}

We need to convert appset to goTemplate issue #46
Then use sprig function lower for example

  template:
    metadata:
      name: addon-{{.name | lower}}-{{.values.addonChart}}

This will address when user see the following error

Error: metadata.0.name a lowercase RFC 1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. '[example.com](http://example.com/)', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')

Found a better solution for this use {{nameNormalized}} ('name' but normalized to contain only lowercase alphanumeric characters, '-' or '.') instead of {{name}}
