fix: Add CODE_SNIPPET_USE_AUTO_CONFIG environment variable

[ddl-rliu]

TL;DR

The inputs/outputs Python code snippet leads to a "Failed to connect" error

Introduce the environment variable CODE_SNIPPET_USE_AUTO_CONFIG, to control whether the config object in the inputs/outputs Python code snippet is automatically constructed i.e. Config.auto(). This will tend to use the admin.endpoint that users can set in their ~/.flyte/config.yaml

It can be left unset to keep the current behavior e.g. uses Config.for_endpoint(window.location.host)

Complete description

Users already configure flytekit in ~/.flyte/config.yaml to set admin.endpoint to the correct gRPC endpoint. We can leverage this by using Config.auto() auto config, and building the code snippet around this Config.

Tested fix correctly shows the new code snippet when setting is enabled:

Tested fix uses current behavior when setting is not enabled:

Could you just pass isHttps in as the 2nd parameter to Config.for_endpoint?

[ddl-rliu]

For context, this follows the nested ternary pattern that I've seen e.g. here

flyteconsole/packages/oss-console/src/components/flytegraph/ReactFlow/transformDAGToReactFlowV2.tsx

Lines 199 to 205 in 7636e32

	const typeOVerride =
	// eslint-disable-next-line no-nested-ternary
	isStaticGraph === true
	? dTypes.staticNode
	: isUnFetchedDynamicNode(node)
	? dTypes.nestedMaxDepth
	: undefined;

Since python booleans aren't one-to-one with JS booleans, to pass in isHttps as a param it would have to look like

const insecure = isHttps ? "False" : "True"
 ... `Config.for_endpoint("${window.location.host}",${insecure})`

which I wasn't sure would be much clearer.

Yeah, the reason I asked was for exactly the reason the ignored eslinter calls out
https://eslint.org/docs/latest/rules/no-nested-ternary

It's fine to use the existing style / pattern they have here -- when in Rome :)

Gotcha! Okay, updated it here: df63f99
