dpdk: Use DPDK 19.11.6 release.

Modify ci linux build script to use the latest DPDK stable release.
Modify Documentation to use the latest DPDK stable release
19.11.6. Update NEWS file to reflect the latest DPDK stable release.

Note: 19.11.6 is the latest stable release in the 19.11 series.
So OvS 2.13 is updated to use 19.11.6 version
18.11.11 is the final support release for the 18.11 series,
no further support releases for 18.11 series are expected.
So, both OvS 2.11 and 2.12 are updated to use 18.11.11.
