The task 56586 is for adding tests against the collection converted
format to the tox/travis CI to capture a problem before merging the
pr, if any. It'd be helpful to find out bugs in the conversion tool
lsr_role2collection.py, as well. The source of this commit is located
in linux-system-roles/template. They are synced by auto-maintenance/
sync-template.sh, then manually adjusted to the network role.
.travis/runcollection.sh is the test script. tox.ini is modified to run
it in the tox/travis CI. The script downloads lsr_role2collection.py,
then converts the network role into the conversion format in the working
directory .tox. In the collection, it runs a set of tests black, flake8,
yamllint, py38 to check the converted result.
Ethtool features should use underscores instead of dashes. A
warning shows in case dashes used, and it fails if underscore and dashes are
mixed. Unit tests and integration tests have been added. Since nm already
needed underscores, the string processing that was made in nm_provider is now
unneeded and therefore removed.
