Show size of files in Download section

[samsonbek]

In "Getting started" page, where there is list of files to download, we need to show file sizes too.
Size info could be obtained from same link, as download link, just replace get to info:
download link -> https://cdn.subut.ai:8338/kurjun/rest/raw/get?name=subutai-p2p.deb
info link -> https://cdn.subut.ai:8338/kurjun/rest/raw/info?name=subutai-p2p.deb

Response of info looks like this:

[{"id":"dbb5f882-318a-414b-b534-e3837d8b888e","hash":{"md5":"83334a3c2c50db9aa3d4ff29a204560b","sha256":"4cbeda3eea1af98154234ec5c11c3cbbcc615e45be4289141cf0d7f4a2717b7b"},"size":2502182,"name":"subutai-p2p.deb","owner":["mike"],"filename":"subutai-p2p.deb"}]

take size value from this reponse, convert to KB or MB.

Use AJAX to obtain data.
