Move to using kedge schema structs in kedge init

[surajssd]

Right now we use golang templates, so we should think of moving to using kedge schema a.k.a. structs that kedge has defined. Golang templates tend to get complex very soon. With structs we can add more features and have easier control on what is to be generated.

When we start doing more complex generation it might become a bit complex with templates, I agree.

The thing is that we actually lose control over what is generated if we start serializing Kedge schema. For example, we lose ability to add comments.
The idea was that generated Kedge file should also contain some comments when we start doing a little bit more than just image and ports.

I'm marking this as a low priority. What we have is working right now. We can start thinking about this once it becomes an issue, or we need add more stuff to kedge init

@surajssd @kadel Now we have golang structs in kedge init instead of templates, shall we close this ?

[surajssd]

we are using golang structs but not kedge schema structs yet
