Introduce --insecure-skip-tls-verify option for self-signed HTTP git URLs

[alexmt]

Describe the bug
It is impossible to connect repositories using HTTP git url if git server uses self-signed certificate.

To Reproduce
Steps to reproduce the behavior:

1. Try to connect repo using argocd repo add https://<url> --username <username> --password <password> --insecure-ignore-host-key
2. The connection fails if server uses self signed cert: x509: cannot validate certificate for <host> because it doesn't contain any IP SANs

Expected behavior
Repository should be successfully connected.

This bug is invalid. --insecure-ignore-host-key only apply to SSH host keys and does not make sense in the context of https URLs / x509 errors.

For https URLs, the solution is to supply the self-signed certificates of the repo-server and api-server. Otherwise we can decide to introduce an --insecure-skip-tls-verify flag, so that self-signed certificates to https git repos are accepted.

I will convert this bug to an enhancement for that request.

@jessesuen Having a way to add insecure https git repos would be great. In my case, I don't use argocd cli at all. Another option could be to add a field for pasting your CA in ArgoCD UI's when adding a git repo. That's the way Rancher-UI handles custom CA's for pipelines.
