build: deploy API documentation #245
Description
It seems https://tarantool.github.io/tarantool-java/ it the proper place for the API documentation (now I see outdated API docs are on http://tarantool.github.io/tarantool-java/apidocs/index.html ; but I don't know to reach them from the previous link).
I think we should perform deploy manually as part of the release process (or even store separate documentation for each release) to don't confuse users with not-released-yet changes.
Maybe connected with #244.
