[TASK] Migrate various names to conform KubeVirt conventions

[starbops]

Due to the upcoming project migration schedule, we have some tasks that need to be done before the migration to ensure smooth progress.

One of the tasks is to renaming the CRD and change the API group of it to conform the KubeVirt convention:

• Changing from KubeBMC to VirtualMachineBMC
• Changing from zespre.com to kubevirt.org

Also, the components kubebmc-controller and kbmc should be renamed to virt-bmc-controller and virt-bmc, respectively.

Finally, the project's name will be changed to KubeVirtBMC to convey that this project is targeted to work with KubeVirt.

P.S. This is a follow-up issue of #1.
