Flyte

Hi team :wave: – wondering what options are available for overriding the default `image_config` when using pyflyte – ideally via environment variable like `FLYTE_INTERNAL_IMAGE` or `~/.flyte/config.yaml` . In particular, when running
```pyflyte --verbose run --remote hello-world/example.py hello_world_wf

Running example.hello_world_wf with ...
image_config=ImageConfig(default_image=Image(name='default', fqn='<http://cr.flyte.org/flyteorg/flytekit|cr.flyte.org/flyteorg/flytekit>', tag='py3.9-1.10.2'), ...```

This is for a bare-bones workflow
```from flytekit import task, workflow

@task
def say_hello(name: str) -&gt; str:
    return f"Hello, {name}!"

@workflow
def hello_world_wf(name: str = 'world') -&gt; str:
    res = say_hello(name=name)
    return res```
I'd expect when `FLYTE_INTERNAL_IMAGE=foo` then the above command would run using `foo` as the image.

Digging into the code <https://github.com/flyteorg/flytekit/blob/e394af0be9f904fbf8be675eaa8b8cdc24311ced/flytekit/configuration/__init__.py#L287-L290> it looks like `FLYTE_INTERNAL_IMAGE` never gets looked at and it runs using the <http://flyte.org|flyte.org> image instead

we'd like to override this via env var or config.yaml, so that it does not need to be manually passed in CLI via `--image` every time

you can take a look at <https://docs.flyte.org/en/latest/deployment/configuration/general.html#evaluation-order-in-podtemplates|pod templates>, which should expose a property allowing you to set the image value

drafted a quick PR to give a particular idea of what my concern/question is <https://github.com/flyteorg/flytekit/pull/2223/files>
