Update alpine base image in Dockerfiles to v3.11

[arthurk]

This PR updates the alpine docker base image to the latest version 3.11

The alpine release notes are available here https://wiki.alpinelinux.org/wiki/Alpine_Linux:Releases

Testing

Docker build the images. CI should show us if this is successful.

Coverage remained the same at 77.583% when pulling 298288f on bump-alpine into 0b81354 on master.

We could test this now I think if you resolve the merge conflicts!

@arthurk The error is a bit hidden behind "Start daemon services" step, probably because docker-compose logs returns a normal exit status. Something about missing OpenSSL so I think it's related to the alpine bump. Here's the relevant logs:

ERROR: for watcher  Container "7cae21c7e36b" is unhealthy.

ERROR: for watcher_info  Container "7cae21c7e36b" is unhealthy.
ERROR: Encountered errors while bringing up the project.
Makefile:12: recipe for target 'start_daemon_services' failed

I'll submit a separate PR to fix this silent failure.

[unnawut]

LGTM now. Thank you! Let's merge omisego-images/docker-elixir-omg#40 and get the stable image tag onto this PR.

[unnawut]

Can use omisegoimages/elixir-omg-builder:stable-20200410 now!

[arthurk]

@unnawut it's using the new stable image now

[InoMurko]

Can you pls update snapshots.ev and circleci/config to use the same stable image?
