blockscout docker all-in-one image

[sevenzing]

The idea is to have one docker image to start blockscout. Frontend and backend currently work with apline images, however rust services primarily use ubuntu

I suggest to try to move all services to apline image and build single Dockerfile with

• smart-contract-verifier
• eth-bytecode-db
• visualizer
• sig-provider

• stats -- currently it has requirement to start on indexed blockscout, so for now let's build this image without stats
