Tempest concurrency seems to be breaking tests

[Alex Kavanagh]

Tempest concurrency of more than 1 seems to be breaking tests.

It's not clear whether this is a nova-lxd <-> pylxd <-> lxd issue, or a problem in tempest.

As a temporary measure, setting the TEMPEST_CONCURRENCY env variable to 1 seems to clear the problem.

    Fix bug in scenario/manager and cover it with pep8

    manager.py had a syntax error which caused the module to be not
    installable. This wasn't picked up in testing. This fixes the bug
    and adds pep8 coverage to the nova_lxd_tempest_plugin so that the module
    always remains installable.

    Also, this fixes the tempest concurrency at 1. See the related bugs.
