Improve error messaging for invalid headers

See original GitHub issue

Library or service name Azure.Storage.Blobs

Description When an InvalidHeaderValue exception is thrown, information as to the header and its invalid value could be included in the exception (apparently it was, in past versions of the SDK). This would assist developers with troubleshooting and would make situations like this less likely to occur.

Can’t the header name and value be parsed from that?

We do parse those into RequestFailedException.AdditionalInformation today.

I thought that was displayed by default? If it’s not, we should fix that. If it’s not discoverable enough, we should consider post facto client-side validation to make it clearer.
