feat: Create support an external addons

[matheusmazzoni]

Description

In this new functionality the idea is
we have the possibility to install external/additional addons, that is, the addons that are not installable by the aws_eks_addon resource.

Motivation and Context

Currently there are components/addons that are ideal for a functional installation of an EKS Cluster, at least to have a good functioning and that it is possible to implement applications without great complexities.
We have examples of addons that fulfill this role: Cluster Autoscaler, Metric Server, AWS Load Balancer Controller, etc.
In this way, the creation of additional/external addons opens the possibility of implementing several others (currently we contemplate only Cluster Autoscaler).

@bryantbiggs Thanks for the tip! It was inside the blueprints repository.

whats inside the blueprints repository?

[matheusmazzoni]

Sorry for my bad english haha.
I just realized that this code is in another repository.
In addtional, @bryantbiggs, there are two repositories with addons: the one you showed me (terraform-aws-eks-blueprints-addons) and this one terraform-aws-eks-blueprints. Which one the "community" recomends to use or it's better?

Modules/addons are no longer available in https://github.com/aws-ia/terraform-aws-eks-blueprints and the last remaining helper modules will be removed soon aws-ia/terraform-aws-eks-blueprints#1699
