openNetVM to use latest version of DPDK

[Vivek-anand-jain]

The current version of ONVM is using DPDK v18.11. The DPDK project has released a newer version sometime back in May 2020. The release notes can be found here: https://doc.dpdk.org/guides/rel_notes/index.html

I find some constants/function names have been changed since DPDK version 19.11: https://doc.dpdk.org/guides/rel_notes/release_19_11.html (section 3.3)

Note: The DPDK has announced that they will deprecate build with make in future releases and use meson and ninja for future releases. https://doc.dpdk.org/guides/linux_gsg/build_dpdk.html#installation-of-dpdk-target-environment-using-make

This will be a good thing to update. We will need to:

• update APIs/constants
• update our install script and guide to use meson/ninja
• update cloudlab profile
• Check for any major new features which we can benefit from
