[KEP 0025] Template toYaml function

[porridge]

What this PR does / why we need it:

This KEP describes addition of a function called toYaml for use in the operator templates.

Do we need a KEP for this? IMO, the motivation is already covered in #1221. And adding a toYAML function that marshals an interface{} into YAML is maybe 10 lines of code. The only thing needed is an implementation of KEP-24, that allows parameter values that are more complex that string.

Do we need a KEP for this?

So, your comment on KEP-24 that toYaml should not be a part of that KEP somehow made me think that it's big enough to warrant its own KEP. Then the way I read the guidelines I thought that it might be borderline, but does not hurt. So I just did it :-P

If you think it's a no-brainer please just hit the approve button 🎉 :-)

@porridge You're right and I don't want to discourage anyone from creating new KEPs. Just be aware that a KEP has a bit more overhead :)
