Add additionals api modules

[Makentoshe]

This modules should contain builders for urls used in different api versions (mobile or native).

We might replace java-dependent retrofit with custom solution. This also helps us to migrate to MMP project

For example:
val url1 = HabrahabrNative.articles().article().getById(articleId).build(userSession)
val url2 = HabrahabrNative.articles().top().daily().get(page).build(userSession)
val url3 = HabrahabrNative.articles().article().voteUp(articleId).build(userSession)
val url4 = HabrahabrNative.articles().article().comments(articleId).getAll().build(userSession)
val url5 = HabrahabrNative.comments().comment().getById(commentId).build(userSession)
