Private Git repositories support

[netandreus]

I have local GitLab deployment (on-premise) and using self-signed SSL certificate (as I can issue regulary SSL for the internal domains like git.mycompany.internal). Now I can't add this repo to the OpenCode Manager as it falls with an error "SSH host key verification failed or was rejected by user".

I already added

git config --global http.https://git.mycompany.internal.sslVerify false

but looks like it doesn't work as you have implicit this.verifyHostKeyBeforeOperation(repoUrl) check.

Could you please add to the the "Add Repository" form small checkbox "SSH host key verification" so I can disable it for such cases?
