Kotlin 1.5 borked

[Arneball]

I tried bumping kotlin version to 1.5.10 and it blows up in kotlinpoet.
I forked and bumped kotlinpoet to 1.8.0 and it worked, so I guess it is not overly complicated.

However, a new warning appeared:

Deprecation warning: converting xxx.BaseResp.OtherResponse to TypeName. Conversion of TypeMirror and TypeElement is deprecated in KotlinPoet, use kotlin-metadata APIs instead.
Deprecation warning: converting xxx.BaseAction.FormAction to TypeName. Conversion of TypeMirror and TypeElement is deprecated in KotlinPoet, use kotlin-metadata APIs instead.

I have a fix half implemented but I was blocked on some other things. I'll check if I can fix it now that 1.5 is released
