Subject: [PATCH] Move remaining feature interfaces into
 `Microsoft.AspNetCore.Http.Features` package and namespace - #590, also
 related to #561 - move feature interfaces from `Microsoft.AspNetCore.Http`
 package - move required classes from `Microsoft.AspNetCore.Http.Abstractions`
 package - move `ISession` and `WebSocketAcceptContext` to
 `Microsoft.AspNetCore.Http` namespace (#590)

nit: remove transient dependencies listed in `Microsoft.AspNetCore.Http.Abstractions`'s `project.json`
