'tox -e cover' fails

[Frank Zdarsky]

'tox -e cover' fails, as the testr option "--coverage-package-name" is not recognized. As a result, the Jenkins job "os-net-config-coverage-ubuntu-xenial-nv" fails (see example log below).

This seems to be a known issue [0] and a work-around would be to use `test` instead of `testr` for [testenv:cover].

    Fix 'tox -e cover'

    'tox -e cover' fails as --coverage-package-name option for 'testr' is
    not recognized. A work-around proposed by Infra team (see
    https://bugs.launchpad.net/neutron/+bug/1454772) is to replace 'testr'
    with 'test'.

    This patch implements this change and adds the cover/ directory to
    .gitignore.
