Update screwdriver.yaml

[dwighthubbard]

This is to address the lack of manylinux1 wheels as specified in issue #137

Add manylinux1 support and run functional tests against manylinux1, manylinux2010 and manylinux2014 packages

The new workflow based on the screwdriver.yaml in this pull request looks like:

Is there a way to get screwdriver to use the manylinux2010 docker image to build both manylinux1 and manylinux2010 packages? The manylinux2010 auditwheel tool supports that, I don't know anything about screwdriver and if it exports that as an option. That would save a build job.

The manylinux1 build container is based on manylinux5, the manylinux2010 build container is based on centos6 and the manylinux2014 container is based on centos7.

The CI pipeline for this project has 3 package publish jobs defined

  publish_pypi:
    # This template by default in a manylinux2010 container and
    # publishes sdist and manylinux2010 wheels
    template: python/package_python
    environment:
      PUBLISH: True
    requires: [verify_test_pkg, verify_test_pkg_ml1, verify_test_pkg_ml2014]

  publish_pypi_ml1_64:
    template: python/package_python
    image: manylinux1_64
    environment:
      PACKAGE_TAG: False
      PACKAGE_TYPES: wheel
      PUBLISH: True
    requires: [verify_test_pkg, verify_test_pkg_ml1, verify_test_pkg_ml2014]
    
  publish_pypi_ml2014:
    template: python/package_python
    image: manylinux2014
    environment:
      PACKAGE_TAG: False
      PACKAGE_TYPES: wheel
      PUBLISH: True
    requires: [verify_test_pkg, verify_test_pkg_ml1, verify_test_pkg_ml2014]

The three publish jobs this pull request has use the same package_python template but differ in the docker container image they are using. This allows the packages to be built with 3 different manylinux docker containers.
