@deepmap-marcinr, could you, please, share what do you plan with this PR?

This generator is used in the InfluxDB Client Go to generate client stubs from the InfluxDB server very complex swagger. As there are many enums, these changes are necessary. This generator even fails on this swagger due to changes in #181 without this PR.

It is becoming harder and harder to maintain this PR due to its complex changes to schema processing.

Maybe, in order to don't break generated interfaces and make this PR better to merge, this could be done by a cmd option?
However, in order to make this optional, it would require complex changes, which I don't know now.

I'd like to merge this, but I'm going to break people, that's the part that is difficult to deal with right now.

My plan is to make a V2 version of this library which pulls in a number of breaking changes, but more importantly, we're going to version the templates separately from the tool itself, to make future changes easier. However, it's going to take me a while to get there.

I'm leaning towards merging this end explaining what happened in release notes.

Thanks for merging this, @deepmap-marcinr

This may be a weird question on a long closed issue but I don't believe this actually type checks the enums, since GeneratedEnumType("ANYSTRING") will return a valid GeneratedEnumType, and when this is unmarshalled any string would also be a valid GeneratedEnumType.
