OPNFV KVM4NFV CICD: Scripts for creating Rpms & Debians for Kernel, Qemu

This patch contains the files for generating rpms & debians for both kernel
& qemu changes, as part of kvmfornfv project development. The scripts will be
triggered to build kernel-rpm & qemu-rpm packages inside centos docker, and
kernel-debian & qemu-debian packages inside ubuntu docker, as part of the
CICD process.
After the new builds are ready, they will be deployed on the pharos testbed
for verification. Later, these will be consumed/triggered by verify/daily
Releng JJBs.

+The "ci" folder consists of-
+
+build.sh --> builds rpm packages (if -p package option is  passed as "centos"
+or in default case) by calling build_rpm subfolder files ; builds debian
+packages (if -p package option is  passed as "ubuntu") by calling build_deb
+subfolder files; builds both debian and rpm packages (if -p package option is
+passed as "both").
+
+build_deb --> contains the files required to build debian backages for kernel
+and qemu, inside ubuntu docker.
+
+build_rpm --> contains the files required to build rpm backages for kernel and
+qemu, inside centos docker.
+
+envs --> contains the host and guest setup+configuration files.
