Command list-verifier-tests failed after adding murano tempest plugin

[Sofiia Andriichenko]

tempest - master
murano - master

steps to reproduce:
1. install rally
2. clone tempest and murano to /var/lib/
3. Execute:
source openrc
rally-manage db recreate
rally deployment create --fromenv --name=tempest
rally verify create-verifier --type tempest --name tempest-verifier --source /var/lib/tempest --system-wide
rally verify add-verifier-ext --source /var/lib/murano
rally verify configure-verifier --extend /var/lib/lvm_mcp.conf
rally verify configure-verifier --show
rally verify list-verifier-tests

expected result: list of tempest tests

actual result: http://paste.openstack.org/show/614045/

    Use default credentials if None has been passed

    Reason - credentials do not load on import in tempest plugin clients.py
