After investigation, we found that tricircle tempest plugin config tricircle/tempestplugin/config.py is using the tricircle config defined in tricircle/common/config.py which is overriding the tempest config
which leads to the failure of tempest cli and the tempest plugin config implementation is also wrong. It should oslo config to populate required tempest config required for tricircle.

Apart from that after doing testr list-tests, It is also failing

    Remove tricircle tempest plugin

    * The tricircle projects contains the skeletion of tempest plugin and
      there is nothing implemented with in the plugin and the existing plugin
      extension is breaking the tempest cli. So it is better to completely
      remove the plugin.

    * In future, if we need tempest plugin for tricircle, we need to implement
      in a seperate repo.
