devtools: move e2e/docker/*

The e2e docker setup is moved to devtools, since it will also be useful
for developing locally.

Moved and changed references for:
- e2e/docker/Dockerfile.frontend -> devtools/docker/Dockerfile.frontend
- e2e/docker/docker-compose.yaml -> devtools/docker/docker-compose.yaml
- e2e/docker/run.sh -> devtools/run_e2e.sh
