Previously all of the VM provisioning code was intertwined with the VM lifecycle code e.g. The VSphere specific code is mixed with Redis code. This makes it impossible to add aditional providers or disable VSphere integration. This commit begins the process to refactor the VSphere code out of the lifecycle code by introducing the concept of VM Providers. A Provider will contain the logic/ code to manage VMs i.e. create/destroy/inquire. Therefore the Pool Manager can query a strict interface into one or more Providers. Initially only a VSphere provider will be available. This commit adds the base class for all providers and describes the API or contract that the Pool Manager will use to manage VMs.
