Fix wildcards in Retrofit services and increase read timeout

[gabrielfeo]

Fix issues found using the feature preview spec:

• Add @JvmSuppressWildcards to avoid runtime Retrofit errors. When specs generate strongly typed code, such as kotlin.collections.List<ApiType>, for Java interop this is java.util.List<? extends ApiType> which is not allowed by Retrofit.
• Increase default read timeout and support overriding it, as some endpoints would timeout with default 10s
• Also add full request logging if debugLoggingEnabled and fix overriding -Pversion, which was always overwritten by the buildscipt
