Why are the changes needed?

flyteorg/flytekit#2654 adds an echo task, which can be used in the conditional workflow. However, it doesn't work out of the box. The platform engineer has to update the propeller config to enable it.

What changes were proposed in this pull request?

Enable it by default.

How was this patch tested?

import typing

from flytekit import ImageSpec, conditional, task, workflow
from flytekit.core.task import Echo

new_flytekit = "git+https://github.com/flyteorg/flytekit.git@2349ceeaf74fe6449b66eee54be5667aec0b45ab"

custom_image = ImageSpec(
    registry="localhost:30000",
    packages=[new_flytekit],
    apt_packages=["git"],
    builder="default",
)


echo1 = Echo(name="echo", inputs={"a": typing.Optional[float]})


@task(container_image=custom_image)
def t1(radius: float) -> typing.Optional[float]:
    return 2 * 3.14 * radius


@workflow
def wf1(radius: float) -> typing.Optional[float]:
    return (
        conditional("shape_properties_with_multiple_branches")
        .if_((radius >= 0.1) & (radius < 1.0))
        .then(t1(radius=radius))
        .else_()
        .then(echo1(a=radius))
    )

Can we build an image and check it in the configmap?
