### Description

This issue should be resolved by simply adding `ulimits` parameter to `DockerOperator` that is directly passed to [`create_host_config`](https://docker-py.readthedocs.io/en/stable/api.html#docker.api.container.ContainerApiMixin.create_host_config).

### Use case/motivation

Currently applying custom `ulimits` is not possible with `DockerOperator`, making it necessary to do some hacky entrypoint workarounds instead.

By implementing this feature, one should be able to set Ulimits directly by giving a list of [`Ulimit`](https://docker-py.readthedocs.io/en/stable/api.html#docker.types.Ulimit)-instances to `DockerOperator`.
