Error when running unik daemon on Windows: Raw-mode is unavailable courtesy of Hyper-V

After fixing several issues, I encountered a new issue when running unik daemon.

After googling the error: Raw-mode is unavailable courtesy of Hyper-V (https://stackoverflow.com/questions/50053255/virtualbox-raw-mode-is-unavailable-courtesy-of-hyper-v-windows-10), I found that VirtualBox cannot be used when Hyper-V is enabled. But unik requires Docker. And Docker for Windows requires Hyper-V. So They are contradictory.

Is there any solution to fix it? I can think of some:

1. Remove the use of Docker in unik. In fact, I don't understand why unik uses Docker. Unik is meant to run on Linux originally, and unik can just use Linux commands, why has to run the commands in a Linux container? Utilizing both Docker and virtualization can be complicated.
2. Use Docker toolbox instead of Docker for Windows. Docker toolbox seems not to rely on Hyper-V. So I can use VMware or VirtualBox to hold the Linux VM of the Docker toolbox. I will try it.
3. Use another unik provider than VirtualBox. Because I just want to use unik to understand it first. I didn't have to be bound to VirtualBox. But is there any other local providers that can run on Windows? From the list: https://github.com/solo-io/unik#supported-providers, I didn't see one.

1. unik uses docker because of the complex dependencies that each unikernel compiler requires. between rump, osv and includeOS, there are a large number of dependencies many of which are not portable across platforms
2. for running locally, qemu and VirtualBox are pretty much your only options. you could also run on a cloud provider like openstack or AWS

another option might be to investigate raw mode and if it's something that can be disabled (to be honest I can't recall if that's something we do explicitly in unik)

this is an issue i'd like to see fixed as well; let me know if i can help or provide any other guidance.

I encountered an issue when using Unik with Docker Toolbox, please see: #167
