ICacheProvider calls Start() and provides the region prefix as a
property, which lets us create a dedicated DataCache.
The BuildCache method is called once per record, and reuse by
Nhibernate.
There is no way to configure the cache provider for specific tenants,
thus ignoring it. NHibernate should take an instance instead of a type
for the provider.
Added clear exceptions in provider constructors when settings are missing or invalid.
Refactored cache client configuration and creation into separate class.
Enabled session state cache provider by default in Orchard.Azure.Wew.
Moved all string constants into Constants class.
Got rid of unused implicit module feature of Orchard.Azure.
Added missing settings banner.
Split Orchard.StorageConnectionString role configuration setting up into two separate settings for Media and Settings respectively.
Renamed startup task.
Removed hard coded connection string and container name from AzureFileSystem, making it truly reusable.
Deleted old module Orchard.AzureBlobStorage.
Moved all Azure code into Orchard.Azure module, deleting the old Orchard.Azure project.
Cleaned up Web.config and Config\* files in Orchard.Web and Orchard.Azure.Web.
Publishing now works for both Release and Debug configurations (previously worked only for Debug).
Added missing module project Orchard.AzureBlobStogare to Orchard.Azure.sln and added a reference to it from Orchard.Azure.Web.csproj.
Created separate solution folders Modules and Modules.Deprecated in Orchard.Azure.sln to be consistent with Orchard.sln.
Cleaned up web.config transformation files.
Upgraded Orchard.Azure, Orchard.Web and Orchard.Azure.Web to new storage client (version 2.0).
Removed duplication between Orchard.Azure and Orchard.AzureBlobStorage (the latter is now just a thin wrapper over the former).
Added proper transformations for log4net.config and HostComponents.config in both Orchard.Azure.Web and Orchard.Web (recreating what was previously done by custom MSBuild logic in the project files).
