When using the filestate backend (local files and cloud buckets) there is no protection to prevent two processes from managing the same stack simultaneously.
This PR creates a locks directory in the management directory that stores lock files for a stack. Each backend implementation gets its own UUID that is joined with the stack name. The feature is currently available behind the `PULUMI_SELF_MANAGED_STATE_LOCKING=1` environment variable flag.
This will allow us to start publishing dev channel builds as

This change adds schema and codegen support for plain properties which
are emitted typed as the plain type rather than wrapped as an `Input`.
Plain properties require a prompt value and do not accept a value that
is `Output`.
This change avoids `RuntimeError: There is no current event loop in thread '<thread_name>'` errors when passing a resource as an input multiple times when using mocks.
The problem is that when using mocks, we deserialize the gRPC inputs before passing them to the user's mock methods. Deserializing inputs doesn't typically require an event loop, however, during deserialization of resource references, we end up creating some instances of `Future`, which does require an event loop to be present for the current thread. If this is done multiple times for a resource, it's possible that `deserialize_properties` will be called on an asyncio thread that doesn't yet have an event loop, resulting in the error being raised.
The error does not occur when only passing the resource reference once because typically the thread (e.g. `asyncio_0`) used in that case will have already had an event loop created for it due to the use of the internal `_syncawait` when _serializing_ the source resource's properties, which ensures an event loop is set for the thread.
The fix is to ensure an event loop is created for the thread in the mocks implementation before calling `deserialize_properties`.
When passing a package source as part of a `dotnet add package` in
our acceptance testing framework, dotnet was then trying to use that
package source for the restoration of other packages in the csproj
file.
We have removed passing the source to dotnet add package add
and replaced it with adding a machine level package source via
dotnet nuget add source command
this is the more correct way to work and will allow us to be able
to search multiple locations as part of the dotnet restore command
