* Refactor activity work item with support for activity input
* Serialize scheduled activities as part of workflow state
* Add signal to schedule child activity

* Use ShortGuid for identity
* Cleanup WorkflowServer host
* Fix flowchart next activity scheduling bug
This fixes a bug where the Flowchart activity would schedule connected activities regardless of the outcome of the completed activity.
* Cancel activity execution when cancellation token is triggered.
* Enable user to handle HTTP endpoint validation failures as outcomes
* Don't respond with full details in case of HTTP Endpoint faults for security
* Implement Incident Strategy interface and resolver

* Incident roundtrip and fix workflow instance realtime updates
* Remove unused variable
* Add integration tests
* Initial implementation of workflow inbox, submission and delivery
* Implement persistence providers
* Update EF Core migrations
* Rename Services to Stores in Dapper module
* Use default serializer for primitive arrays
* Update MongoDB provider to map BookmarkId to be primary key
* Implement MongoDB provider for activity execution logs
* Use EF Core by default
* Fix private JSON constructor logic
* Incremental work on context activity
* Add extensions to get and set context params

* Update polymorphic object converter to skip start array
* Update activity execution middleware to handle background execution
* Fix sample program to include activity middleware for contexts
* Comments and cleanup
* Refactor HTTP route table population
* Update workflow definition EF store to use abstract IWorkflowInstanceStore
This decoupling is necessary, because the application might not be using EF Core, but e.g. Elasticsearch
* Move workflow state persistence to the default workflow runtime feature
* Update JS handler to provide access to variables during trigger indexing
* Configure Proto.Actor runtime with different workflow pipeline
* Add sample using Proto.Actor runtime
