Feature Overview:
This feature brings support of PCI device grouping on Cyborg side and provision of such groups as single device for allocation to VMs on Nova side. Key functionality provided by this feature is detection of device grouping on HW level made for example by NVLink.

Goals:

• To enable PCI groups management on Cyborg side
• Nova placement compatible provision of the groups for allocation to VM instances
• Refactor current lspci based device discovery as it bring performance issues for placement in pci driver
