Tasks

1. Check and removed unneeded application protocols from the connection config.

I think the application protocols are just needed for HTTP related stuff? Its possible we don't need any of them. So if tests succeed with an empty list that that's all we need to do for this issue.

[tegefaulkes]

Setting an empty array results in a TlsFail and no connection attempt. The minimum needed seems to be that we set at least 1 protocol, I don't think it matters what one we use.

[tegefaulkes]

I'll trim the list down to ['http/0.9'].

[CMCDragonkai]

Hold on this should be configurable by the end user. It's probably needed for when QUIC would be used for HTTP3.

However are you saying we need a default item in the list...?

In that case, is there an ALPN intended for just basic QUIC data?
