staging: Update backend containers from their docker-compose.yml files

[abitrolly]

There are no single container for each backend component that we need to reach from frontend API, and maintaining list of container dependencies for every backend component in multiple places is too much of a hassle.

We've already got up.sh script, so let's make it handle dependencies and leave in docker-compose.yml only containers for cyber-ui itself.

Conventions needed for staging server setup:

• repos for all components are cloned into $HOME on staging
• component compose file is located in /devops/staging/docker-compose.yml

up.sh then pulls all repos and runs docker-compose.yml up for every component.
