v0.5.0

You can now add repositories to Helms repository index without
defining them in the charts.yml.

This allows you, for example, to always add specific
repositories when executing kubecrt on your CI server:

kubecrt --repo=myname=https://my-repo-address charts.yaml

apiVersion: v1
charts:
- myname/chart1: {}
- myname/chart2: {}

the above now works, because the myname repository is already in the index, so you don't have to specify the repo key for both charts.
