Concurrency supported in Smoke Tests (#7169)

* .NET smoke Test Sample

Performs functionalities with Key Vault, Identity, Event Hubs and Blob Storage Track 2 SDKs.

* Env Variables names changed

The names were changed to match the name convention for environment variables.

* Update .gitignore

* gitignore updated

A gitignore file was created in the SmokeTest folder, and now all launchSettings.json files are being ignored.

* Exit Codes, PascalCase and refactoring of the static methods.

Work based on the reviews from the PR #6652. The public methods are now in PascalCase, the methods does not longer return English strings, instead they return booleans or Exceptions.  And Exit Codes handling was implemented.

* Class names changed

Class names were changed to match the following pattern: <service>Test. Example: BlobStorage -> BlobStorageTest.

* Comments

XML comments were added and some unnecesary comments were deleted.

* Higher order functions

Use of higher order functions to dry up the code.

* Test classes refactured

Drying up the code by using high order functions.

* Create CosmosDBTest.cs

* Cosmos DB implementation

Tests done with Mirosoft.Azure.DocumentDB SDK.

* Update CosmosDBTest.cs

* Update CosmosDBTest.cs

* Unnecessary blank lines removed

* ExecuteTest typo

* Base class deleted

The samples not longer need the "TestBase" class to run.

* BlobTestSource.tst deleted

This text file is not going to be needed any more since the test Blob is being created within the code.

* Static Classes

All classes are now static.

* Pair programming comments

* Concurrency support

* License headers added

* License header added

* Adapted for concurrency

* Use of string interpolation

* Use of string interpolation

* Update EventHubsTest.cs
