2020-02-28refactor: Create distinction between CPU node and coreFabian Mastenbroek
This change updates the terminology in the `opendc-compute` module to make a distinction between CPU node and CPU core, where we primarly work with CPU cores. However, if needed, we also provide information for the different CPU nodes.

2020-02-28refactor: Change from logical processes to simulation domainsFabian Mastenbroek
This change moves the simulator terminology from logical processes to simulation domains. This prevents the clash with "processes" that we are trying to simulate. In addition, simulation domains allows us to reduce the amount of boilerplate and instead allows for simulation modelled using standard techniques.

2020-02-14refactor: Remodel workloads and compute resourceFabian Mastenbroek
This change remodels our model for workloads and compute resources in order to support VM/container functionality where multiple workloads run on a single machine. In particular, we make the following changes: - Move the compute-related source code into the `opendc-compute` module. - Change from application-based model to image-based model, where the image has exclusive access over the machine, instead of applications that share the machine. We may model in the future again applications/operating system, but at the moment, we do not need this granularity, given that the workload traces can be simulated using VMs.
2020-02-14feat: Make ProcessContext a coroutine scopeFabian Mastenbroek
This change makes the ProcessContext implement the CoroutineScope in order to launch local coroutines bound to the lifecycle of the logical process.
