With these settings you can hopefully push several different docker images

## Applying docker build flags
Build flags can be applied using `build_flag_templates`. The flags must be
valid docker build flags.
```yaml
# .goreleaser.yml
dockers:
-
binary: mybinary
image: myuser/myimage
build_flag_templates:
- "--label=org.label-schema.schema-version=1.0"
- "--label=org.label-schema.version={{.Version}}"
- "--label=org.label-schema.name={{.ProjectName}}"
```
This will execute the following command:
```bash
docker build -t myuser/myimage . \
--label=org.label-schema.schema-version=1.0 \
--label=org.label-schema.version=1.6.4 \
--label=org.label-schema.name=mybinary"
```
