    METRON-1316 Fastcapa Fails to Compile in Test Environment

    DPDK 16.11.1 will no longer compile against newer Linux kernels due to an interface change
in the kernel.  
    This can be replicated in the Fastcapa test environment.  We use the `bentos/centos-7.1`
image for the test environment.  In this image, the underlying Linux kernel has been updated
which makes it no longer work with DPDK 16.11.1.
    This change upgrades DPDK to 17.08 in the test environment and also updates Fastcapa to
accomodate a function signature change in the newer version of DPDK.
    I also added the ability to run the same Fastcapa test code under multiple operating systems.
 So now we can validate that Fastcapa runs in CentOS 7.1 and also CentOS 7.4, for example.
 Additional platforms could easily be added.
    I also removed an old Ansible role that is no longer being used.
    ## Testing
    1. Run the following.
        cd metron-sensors/fastcapa/centos-7.1
        vagrant up
    2.  The deployment should complete with a message like so.
        Successfully received a Kafka message from fastcapa!
