Add egress NetworkPolicies

[dan-m8t]

Is your feature request related to a problem?

By default we deploy default-deny ingress/egress rules into our namespaces. This means when I deploy Argo CD into a namespace with NetworkPolicies enabled it won't work because Argo CD is missing these egress rules. For example argocd-application-controller egress repo-server port to the argocd-repo-server. Only ingress rules are created.

Related helm chart

argo-cd

Describe the solution you'd like

A configurable helm value that allows the creation of egress rules when needed or wanted.

Describe alternatives you've considered

For now I disabled our default deny egress rule.
