Add Ubuntu eoan package

[fengzhou-msft]

All current Ubuntu releases can be checked here.

Will modify Release Pipeline later to reflect this change.

A suggestion, jobs related to image build across Linux distributions in azure-pipeline.yml can refactor as this doc Create a multi-platform pipeline.

It does the same job as current but simplify.

Currently the task is running on the same ubuntu system but with different variable(DISTRO, DISTRO_BASE_IMAGE) for docker image, can consider your method without using docker in future refactor.

No related to docker. Like this:

strategy:
  matrix:
    ubuntu1604:
      imageName: 'ubuntu-16.04'
    ubuntu1804:
      imageName: 'ubuntu-18.04'
    ubuntu1904:
      imageName: 'ubuntu-19.04'
    ubuntu1910:
      imageName: 'ubuntu-19.10'
pool:
  vmImage: $(imageName)

No hurry.

No hurry.

Current tasks for building various ubuntu packages are all running on a vm of ubuntu-16.04, but with different docker images. To switch to your way which looks more neat, needs some refactoring.
