Fixes boot failure in devel mode

[pcrespov]

Reference to common requirements.txt cannot be reached in devel containers
because the file is not mounted.
The most cost effective solution is to copy&past common requirements (they
do not change much) since COPYing the file in the Dockefile is more
disruptive

Checklist

• Runs in the swarm in devel mode
