Updated fetchValue() function to handle repo level configuration fall…

…back to org level configuration as fetched

Description

I have updated the fetchValue() function body to fetch both the organization level and repo level configurations which are then merged and returned on call. Repo level configurations as found will be considered as final over organization level configurations.

Related Issue

#422

Motivation and Context

As of right now, the org fallback only works if you have no site config. We should inherit on a row basis so that if a site has a single property (aem.assets.link.type) the rest still falls back to org so you don't have to duplicate your repoId, etc.

To solve this as mention in issue #422.

data was an array previously, and is now an object which means that the data.find will fail on line 60. Now that it's an object, you can just do a lookup

Suggested change

	const data = null;
	// Start with organization-level config
	if (orgConf) {
	data = {};
	orgConf.forEach((item) => {
	data[item.key] = item.value;
	});
	}
	// Override with repository-level config
	if (repoConf) {
	if (data === null) data = {};
	repoConf.forEach((item) => {
	data[item.key] = item.value;
	});
	}
	if (!data) return null;
	const confKey = data.find((conf) => conf.key === key);
	const data = {};
	// Start with organization-level config
	orgConf?.forEach((item) => {
	data[item.key] = item.value;
	});
	// Override with repository-level config
	repoConf?.forEach((item) => {
	data[item.key] = item.value;
	});
	return data[key];

I will be updating the PR to treat data as an array to retain the expected data type of data variable. Pushing objects to an array and updating values inside them if the keys match afterwards, is my approach.

This change and below don't need to be refactored

Hi @chrischrischris , I didn't really understand as to why the path variable is required to be passed anyways.

Since configuration merge is fetched from an exhaustive list of paths. I decided to check whether paths are matching with the expected org and repo level paths, fetch the configurations and merge as required.

All other fetchValue() calls which dont match that path patterns will still fall through and return the value fetched as expected in the original function body.
