Would like to be able to add helm repositories that are selfsigned

Is your feature request related to a problem? Please describe.
When using on prem, I would like to be able to tell the "add repository" to ignore self signed certificate verification check, hub is telling me "the url provided does not point to a valid Helm repository", It would be great if this error message could be improved but looking in the code I think it might be caused by a selfsign error comes from Go Getter(), we should be able to configure the Go.Getter options like skipping the certificate check and adjusting the timeout if desired)

Describe the solution you'd like
Add "ignore verification check" to the add repository UI and push that into the hub.Repository class and onto the NewHTTPGetter.go options in LoadIndex

Describe alternatives you've considered
I've tried using GOINSECURE but that doesn't seem to work

Additional context
This is for on prem, artifactory is https but its self signed.
