Minor improvements and bugfixes

https://www.nuget.org/packages/Dodo.AspNet.SessionProviders.CosmosDb/0.2.10

• BUG FIXED: Sliding expiration not updated when session with exclusive lock does not set dirty flag on session items (contents not changed).
• IMPROVEMENT: Contents and locks are stored in a single container for maintenance simplicity. There is not reason to have two separate containers for locks and contents, because we are really only using DB as a key-value store.
