Introduce ability to accept command arguments to build with DPDK or Linux kernel.

Specify patches to apply, build kernel module RPM and build with a special
version of the kernel.

Also instack_ovs.sh creates a VM for building and initial testing of RPMs and
copies scripts to VMs

build_ovs_rpm.sh builds the RPM according to command line options.
test_ovs_rpm.sh tests the RPM by installing the RPM and running some ovs
commands to create a bridge and dump flows.

Also add two scripts generally to be executed in VM to do actual building and
Testing.

This 2nd series adds the following:

Use fedora spec file for kmod builds. Added Explanations to configuration options.
Fixes in response to review comments. Rename script for clarity and change
references: buildtestovs.sh -> BuildTestOVS.sh
Fix nocheck option, print default options, fix kmod option, fix test of kmod.

For command line options execute build/buildtestovs.sh -h
