add support for integration of includeos

[kartikangiras]

Description

Add support for integration of IncludeOS a unikernel framework executed on top of solo5 and qemu .

Issue

Fixes #126

Implementation Details

• VMMs: Solo5-hvt, Solo5-spt, QEMU
• Networking: Via Solo5 I/O interface and virtio-net
• Block storage: Supported with ext2/ext3/ext4 filesystems
• Network Configuration: the CommandString function detects the assigned IP, Netmask, and Gateway. It formats them into a JSON string and then appends this string to the command line arguments used to boot the unikernel. (The default IncludeOS behaviour).

Hello @kartikangiras ,

thank you for this contribution. Have you tried this PR? Some people have also worked in this issue in the past, but we had troubles with setting the network configuration to IncludeOS through the arguments.

@cmainas I have tested this PR via the unit test cases (pushed in the pr) for network configurations and they pass successfully for this.

Would it be possible to perform an end-to-end test too?
In order to do that you will need to:

1. Create a new image of an IncludeOS unikernel with bunny
2. Run it over your changes
3. Check network configuration (e.g. ping, curl request -- depending on the unikernel)
