Resolves #485 - Add PurgeVariables functionality (#654)
* Trivial - Add VS Code workspace

* Trivial - Add VSCode build task & extra ignore

On GNU/Linux, auto-generated .directory
files should be ignored.

* WIP #485 - Boilerplate for unit test project

* WIP #485 - Add test coverage (Remove/RemoveAll)

* WIP #485 - Implement RemoveAll

* Remove redundant logic, covered by IDictionary

Per the following, the contract for a generic IDictionary,
the Remove method already deals with non-existent keys.

* Resolve #485 - Add PurgeVariables methods

These are convenience methods upon ActivityExecutionContext
and WorkflowExecutionContext, consistent with their current APIs.

Also in this commit are tests for those simple methods.
There's a bit of test-scaffold as well included, such as:
* Autofixture Xunit2 integration
* New project for unit tests
* Customize attribute for avoiding crashes on Autofixture recursion
* Reusable specimen builder for creating IServiceProvider which
  resolves services from Autofixture
* Custonize attribute for a parameter to use that ^^ specimen builder
