Surface better error instead of MOVED errors during a network disconnect in redis clusters 

Updating to allow the creation of RedisResults for mocking

Work around build issue for existing csproj's

Visual Studio tooling will use project.json to restore nuget dependencies
when it finds one beside .csproj. This change uses more specific
<project name>.project.json to specify dependencies.

Use the supplied flags when selecting a server to subscribe to

SUBSCRIBE and PSUBSCRIBE are not write ops and can be
performed on slaved instances, so there's no reason to
explicitly pass DemandMaster when selecting the server.

Instead, use the CommandFlags passed as the parameter to Subscribe()

I don't think 1342 is ever getting fixed, adding yet another workaround.

Configuring the minIoThreads

You can't set the processModel in the web.config  "The processModel section can be set only within the Machine.config" and is confusing to have here to be web.config

Invoked like this:
ruby redis-trib.rb create --replicas 1 127.0.0.1:7000 127.0.0.1:7001
127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005

Note: checked in as a working cluster in the hope most others don't have
to:
ruby redis-trib.rb create --replicas 1 127.0.0.1:7000 127.0.0.1:7001
127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005
(and need ruby, etc.)

Note: we still have unit test fails here, but checking in a working
build.

.Net Core RC2 upgrades to for a 1.604-alpha release

- RC2 project.json format and references
- NuGet.config added since we're on one feed now
- Unit tests minimally running in core - lots of work left here
- Bumps to netstandard1.5 for BufferedStream, but we have net40, net45,
and net46 builds already so this should be low impact.
- AuthenticateAsClient() (synchronous) is no longer in .Net Core, Async
version must be used there now.
- Version bump to 1.604-* (alpha suffix is in via dotnet pack now)
- To pack:
dotnet pack StackExchange.Redis -o .nupkg -c Release --version-suffix
alpha
dotnet pack StackExchange.Redis.StrongName -o .nupkg -c Release
--version-suffix alpha
