[catalog-backend-module-aws] - Ability to define Dependency tags

[ogarbe]

Feature Suggestion

In this plugin, we can define the Owner tag in the general config, but the 4 dependency tags

const TAG_DEPENDS_ON = 'dependsOn';
const TAG_DEPENDENCY_OF = 'dependencyOf';
const TAG_SYSTEM = 'system';
const TAG_DOMAIN = 'domain';

are hardcoded.
It would be good to be able to map these relation as we can do for Owner tag, so that the mapping for these 4 tags can be attached to any AWS tag existing.

Possible Implementation

To implement this, the tags code would need to evolve a bit to replace

const dependencyTags = [TAG_DEPENDENCY_OF, TAG_DEPENDS_ON];
const relationshipTags = [TAG_SYSTEM, TAG_DOMAIN];

by 2 maps of tags
TAG_DEPENDENCY_OF => awsDependencyOffTag
TAG_DEPENDS_ON => awsDependencyOnTag

and the config would propose the ability to force these 4 tag value
