[sassanh]

Things done in this pull request:

1. Add a way to upload files in web-ui
2. Update data structures related to reporting result of the ubo_input in store and in its imperative mode to include files field which is a dict of field name -> file stream.
3. Utilize above items in docker composition input form so that the user can upload a file along the docker composition properties. It should be .zip, .tar.gz, .tar.bz2, or .tar.xz. It will then decompress that file and put its content next to the docker-compose.yml file.

Looks good! please merge together with other approved PRs. I will test the experience after merge. The changes should only impact web UI part I believe.
