Split out ASP.NET Core hosting dependency from 2.1-dev

[nblumhardt]

Although we're targeting the hosting infrastructure with UseSerilog() in ASP.NET Core 2, other environments that use Serilog + MEL may not want this dependency (e.g. Orleans).

Following the naming pattern used by ASP.NET Core 2, I'm working on new Serilog.AspNetCore and Serilog.AspNetCore.All packages here: https://github.com/nblumhardt/serilog-aspnetcore.

Once that's ready to move over into the Serilog org, we can remove the UseSerilog() extension and web sample from this repository.

Is it worth attempting to keep those meta packages in this repo and use a separate build?

[nblumhardt]

Thanks for the suggestion. I thought about it, but the effort maintaining a different build didn't seem worth it. Have had my head down, sorry I missed your comment before charging ahead :-)

(I've left out the All package for now, just needs more fiddling around.)

Tried getting the essentials into the README over there - any thoughts?

Looks good, do we ditch the sample from this repo in favour of that one?

[nblumhardt]

👍 yes, going to strip this repo back a bit, PR incoming :-)
