Add support for SSLKEYLOGFILE

[pcd1193182]

Hey all,

rustls has support for the standard SSL key logging approach (useful when using Wireshark to analyze packet traces. However, hyper-rustls never configures the relevant field. As a result, it is very difficult to debug certain kinds of problems when TLS is in use. Would it be possible to expose this functionality, either by default or through the config builders? Thanks!

There is a From<(H, C)> impl for HttpsConnector that should be able to facilitate this use case. If you'd like a more ergonomic solution, we'd be open to a ConfigBuilderExt method for enabling KeyLogFile.

@pcd1193182 Would you be interested in writing a PR for this, or is the workaround described above sufficient for your needs?

Thus far, the workaround is working for me. It would be nice if it was integrated natively into the ConfigBuilderExt, but it's definitely not critical.
