Add Integration tests

Add integration tests. For the most integration testing part, Remotely can be tested on the local machine, since it uses PS Remoting which we can be manipulated as per the requirement.

What do you mean by integration tests ?

[DexterPOSH]

Integration tests will be where we invoke PS Remotely against the localhost to run some tests and verify the internal workings of PS Remotely e.g all the required PSSession are created behind the scenes, the arguments from Remotely.json are used to configure PS Remotely, and a $Remotely global scope variable is created etc.

In short how it would run against an actual box.

Also I need to add a MD file containing the workflow on how the framework works. I think, I have missed specifying those anywhere.

I will work on these integration tests, which will sort of server the documentation on how PS Remotely internals work.

Fixed in #25

Re-opening this as still not covered all the scenarios.
