### How are you starting LocalStack?

With a docker-compose file

### Steps To Reproduce

#### How are you starting localstack (e.g., `bin/localstack` command, arguments, or `docker-compose.yml`)

docker-compose.yml:
```yaml
version: '3.7'

services:

  localstack:
    image: localstack/localstack:latest
    environment:
      - AWS_DEFAULT_REGION=eu-west-1
      - LOCALSTACK_DEFAULT_REGION=eu-west-1
      - LOCALSTACK_SERVICES=ses
      - LOCALHOST_DOCKER_HOST=unix:///var/run/docker.sock
      - LOCALSTACK_LS_LOG=debug
    ports:
      - '4566:4566'
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
```

#### Client commands (e.g., AWS SDK code snippet, or sequence of "awslocal" commands)

```python
import boto3
from mypy_boto3_ses import Client

CLIENT: Client = boto3.client(service_name='ses', endpoint_url='http://localhost:4566')
EMAIL = 'foo@example.com'

def email_quota():
    resp = CLIENT.get_send_quota()
    print(resp['SentLast24Hours'])

if __name__ == '__main__':
    CLIENT.verify_email_address(EmailAddress=EMAIL)

    email_quota()
    # CLIENT.send_email(
    #     Source=EMAIL,
    #     Destination={
    #         'ToAddresses': ['bar@example.com'],
    #     },
    #     Message={
    #       'Subject': {
    #           'Data': 'string',
    #           'Charset': 'string',
    #       },
    #       'Body': {
    #           'Text': {
    #               'Data': 'string',
    #               'Charset': 'string'
    #           },
    #       },
    #     },
    # )
    # email_quota()

    CLIENT.send_raw_email(
        Source=EMAIL,
        Destinations=['bar@example.com'],
        RawMessage={
            'Data': b'bytes'
        },
    )
    email_quota()
```
