Perform remote backend copy via http

[jonah-iden]

What it does

There is a strong indication that copying the backend to remote systems via http is a faster than using sftp. On my local system copying the zipped theia backend, http was 2.5x faster then sftp. I sadly wasn't able to test it with an actual remote system.

How to test

i created a small docker container here https://hub.docker.com/repository/docker/jonahiden/remote-test-ubuntu-ssh/general you can connect to it via ssh with user: test pass: test also open port 8080 or some other port (other ports need configuration in the theia settings) for the http copy
