expose network capabilities

[alexandrebrg]

What needs to be done ?

• Publish new version of workload with NodePort capability
• Add ability to configure a workload with network exposure
• Ability to detect conflicts between newly requested workload and existing workloads

Why it needs to be done ?

We recently introduced Function workloads, they are not meant to long-live in the project, they are a transitioning workload into VMs with network capabilities.

Moreover, we want users to be able to configure workloads network exposure through configuration, and not through automation (as it's done currently).
