Kotlin client lists (#5729)

* [kotlin] array->List instead of Array

Serialization to/from primitive arrays can cause issues with valid
responses. This commit considers swagger 'array' types as 'List' which,
although not as memory efficient should provide a cleaner interface for
users (and avoid serialization issues).

Also, updates README.md to list new generator and excludes
folder at samples/client/kotlin/bin/, which is not used.

* [kotlin] Move sample under conventional directory

samples/client/kotlin/ -> samples/client/petstore/kotlin/

Updated new.sh to generate client/server/docs into similar structure.
Current documentation generators (cwiki, html, html.md, html2) aren't
following a convention like client/server generators.
