Add ApplicationSet chart

[maruina]

Checklist:

• I have updated the chart version in Chart.yaml following Semantic Versioning.
• Any new values are backwards compatible and/or have sensible default.
• I have followed the testing instructions in the contributing guide.
• I have signed the CLA and the build is green.
• I will test my changes again once merged to master and published.

Changes are automatically published when merged to master. They are not published on branches.

Marked as draft because I haven't tested it yet. Tested with helm3 and kind.

Notes:

• Removed the liveness and readiness probe. See curl to probeBindAddr returns 404 applicationset#123
• Leader election tested but not working. See leader election not working applicationset#124 Tested leader election with 2 replicas and it's working fine.

I had to add maintainers for passing the linting stage. I'm happy to help with that, but feel free to tell me I should remove myself and suggest who should be the maintainers :)

Tested with helm 3

❯ helm upgrade -i argocd-applicationset . --namespace argocd --set installCRDs=false

@OmerKahani the linting is failing because of the CRD version. In the applicationset project is still v1beta1 as per https://github.com/argoproj-labs/applicationset/blob/master/manifests/crds/argoproj.io_applicationsets.yaml, but if I change it to v1 I get the following error

Error: failed to install CRD crds/crd-applicationset.yaml: CustomResourceDefinition.apiextensions.k8s.io "applicationsets.argoproj.io" is invalid: spec.versions[0].schema.openAPIV3Schema: Required value: schemas are required

I think there is probably some work to be done in the appset repo?

Thanks

[maruina]

@OmerKahani do you know who should we ask for an approval?

@maruina great PR! Don't you think that in the future this chart will be merged with a base argo-cd chart?

try to send it in the #argo-helm channel

@kvendingoldo I think there is a plan to move ApplicationSet inside ArgoCD in the future. I was keeping it separated until the merge happens.

Do you think it should already be part of the regular ArgoCD chart? I'm happy to move it there.

@OmerKahani thanks, I'll go have a look
