0.24.0 Delete `lamp`, `remotecv` and `kube2iam-kops` charts

what

• Delete lamp, remotecv and kube2iam-kops charts (for now)

why

• It's outdated (from 2017)
• mysql is no longer available in https://kubernetes-charts.storage.googleapis.com, which throws this error when building the charts

Error: found in Chart.yaml, but missing in charts/ directory: mysql
helm.go:84: [debug] found in Chart.yaml, but missing in charts/ directory: mysql

• lamp needs to be updated to a newer version, e.g. from https://artifacthub.io/packages/helm/bitnami/mysql
