DNS target fails due to hostname checks

[Linuus]

Describe the bug

I'm trying to connect to GRPC (logging etc) at Google. I tried using the dns:// target. When I try to connect to Google I get this error

[error] unable to establish a connection to https://216.58.207.106:443. reason: %Mint.TransportError{reason: {:tls_alert, {:handshake_failure, ~c"TLS client: In state wait_cert_cr at ssl_handshake.erl:2207 generated CLIENT ALERT: Fatal - Handshake Failure\n {bad_cert,\n     {hostname_check_failed,\n         {requested,\"216.58.207.106\"},\n         {received,\n             [{dNSName,\"*.googleapis.com\"},\n              {dNSName,\"googleapis.com\"},\n

As you can see it's a hostname check error. The issue is that the grpc library resolves the DNS to an IP and tries to connect to that, so the hostname check fails (IP vs the google domains in certs).

I believe the fix here would be to keep the hostname around and pass it as the hostname option to mint's connect/4 function. See https://mint.hexdocs.pm/Mint.HTTP.html#connect/4

To Reproduce
Steps to reproduce the behavior:

Connect using dns://

Expected behavior

It should connect and not fail the SNI check :)
