    Improved test coverage for tripleo validator

    The validator run subcommand which was previously without
    any unit test coverage now has it's basic operation mode tested.

    Assertions are placed on calls and return values of the parser.

    The existing test structure was improved with enabling of autospec
    on mocked API.

About [this commit](https://opendev.org/openstack/python-tripleoclient/commit/ea8795d00572dd613f38e91e2285c9b41cba4885) shouldn't we still have some default inventory and/or to retrieve it from something like `--stack`? Right now it is very cryptic to newcomers how tripleo validator should be run, e.g. see discussion in [1970387](https://bugs.launchpad.net/tripleo/+bug/1971070)

This issue was fixed in the openstack/python-tripleoclient 19.0.0 release.
