[v2] CLI should use workload flag to get the selector and assign it to the connector custom resource

[nluaces]

Is your feature request related to a problem? Please describe.
The CLI supports a --workload option, it should use the value of that option to obtain the selector and create the connector custom resource with that selector.

Describe the solution you'd like
The --workload flag will contain the value /resource-name>, e.g. --workload
deployment/backend. These are the resource types to check.

• services
• daemonsets
• deployments
• statefulsets

Additional context
This feature will be available only for kube platforms.
