docker: improved container build time

To enable go modules cache add following to `.env.override`:

```
SHELLHUB_GOPROXY=http://<ADDRESS>
```

Replace `<ADDRESS>` with the address proxy cache URL.

For caching go modules Athens (https://docs.gomods.io) is the recommended
proxy cache but you can use anything else.

To run Athens on `http://localhost:3333`:

```
docker run \
       --name athens \
       -e ATHENS_DISK_STORAGE_ROOT=/var/cache/misc \
       -e ATHENS_STORAGE_TYPE=disk \
       --restart always -d -p '3333:3000' gomods/athens:latest
```

To enable npm modules cache add following to `.env.override`:

```
SHELLHUB_NPM_REGISTRY=http://<ADDRESS>
```

For caching npm modules, Athens (https://verdaccio.org/) is the recommended
proxy cache but you can use anything else.

To run Athens on `http://localhost:4873`:

```
docker run --name verdaccio --restart always -d -p 4873:4873 verdaccio/verdaccio
```

This closes #941.
