Use environment variable for password in Docker

Browse Source 
We were getting an error since we started using the postgres 9.6 image:

```
Attaching to app_1, database_1
database_1  | Error: Database is uninitialized and superuser password is not specified.
database_1  |        You must specify POSTGRES_PASSWORD to a non-empty value for the
database_1  |        superuser. For example, "-e POSTGRES_PASSWORD=password" on "docker run".
database_1  |
database_1  |        You may also use "POSTGRES_HOST_AUTH_METHOD=trust" to allow all
database_1  |        connections without a password. This is *not* recommended.
database_1  |
database_1  |        See PostgreSQL documentation about "trust":
database_1  |        https://www.postgresql.org/docs/current/auth-trust.html
```
