Compatibility with Autofac v6

[alistairjevans]

v6 Compatibility and version dependency checks ahead of release.

Since we took the CLS Compliant attribute out of the main Autofac package, I'm now getting CLS Compliance warnings throughout this integration.

Is this going to be an issue? Do we need to put the CLS Compliant flag back in Autofac?

[tillig]

Autofac isn't actually CLS compliant, I don't think. I forget what it was exactly that started failing.

I'd be OK with removing the CLS compliant flag from this integration if we can't put it back on core Autofac.

DiagnosticSource isn't CLS Compliant, hence Autofac can't be either; interestingly none of the .NET Core libraries are now, so it feels like CLS compliant is less useful nowadays anyhow.
