Update Ubuntu CI version to 20.04 and Cuda 11.1. This helps ensure MXNet to work well on recent Linux distributions (while ensuring it continues to work well on ancient distributions based on the CentOS7 CI pipeline)

Thanks to @josephevans who unblocked this update via #19017

Hey @leezu , Thanks for submitting the PR
All tests are already queued to run once. If tests fail, you can trigger one or more tests again with the following commands:

  • To trigger all jobs: @mxnet-bot run ci [all]
  • To trigger specific jobs: @mxnet-bot run ci [job1, job2]

CI supported jobs: [unix-cpu, centos-cpu, windows-gpu, miscellaneous, sanity, windows-cpu, edge, unix-gpu, clang, website, centos-gpu]

Note:
Only following 3 categories can trigger CI :PR Author, MXNet Committer, Jenkins Admin.
All CI tests must pass before the PR can be merged.

This helps ensure MXNet to work well on recent Linux distributions (while ensuring it continues to work well on ancient distributions based on the CentOS7 CI pipeline)

* Preserve Ubuntu 18.04 images for TensorRT pipeline as NVidia failed to make TensorRT available for Ubuntu 20.04

Hi @leezu .
This PR deleted option(USE_CPP_PACKAGE "Build C++ Package" OFF) from CMakeLists.txt which is a breaking change.
I tried for two days to build MXNet from source on Windows, only to find out that my given USE_CPP_PACKAGE=1 option does not exist anymore. The option BUILD_CPP_EXAMPLES =1 also doesn't seem to enable it.

Building the cpp-package on Linux and Mac via the Makefile still works.
Was this intended or done by accident?

@QueensGambit the CPP package was removed as part of 2fbec60 as it relied on deprecated APIs. It's pending refactor to be compatible with the supported C APIs. You can follow #20131 for status

This PR removed USE_CPP_PACKAGE as it was missed in 2fbec60

Thanks for the info @leezu .
However, I am a bit confused because I was still able to build the CPP-Package with Intel-MKL back-end on Linux and Mac for MXNet 1.8.0 (2fc0706).

You can still use the v1.x branch if you want to have backwards compatibility. For the master branch, contributions are very welcome. You can see #20131 for a current PR that implements the CPP package in the master branch. Note that the master branch is in preparation of MXNet v2, which is not completely backwards compatible with v1
