Seperated Create_Workspace as a seperate XML task

Create_Workspace is used used in XML files instead of directly being
executed in DeployObject(). This can be problematic if we deploy
multiple services on the same host, since a previous workspace will be
deleted. Also, it removes futile git clones.

There are other XML steps (CppCheckAnalysis, LicenceAndFormattingCheck,
BuildImage, BuildProxy, BuildClusterImage) that implicitly called
Create_Workspace. Those calls have been removed and care has been taken
to insert the corresponding Create_Workspace steps in the XML.
