Revert "Added neutron cli test case"

This change causes issues in parallel run, because routers
can disappear after listing.

The safe way would be to create the router by the test itself,
and maybe wait for scheduling.

Or using a pre configured router for example router1 created by
devstack.

For now it should be reverted.

This reverts commit 693db20aa8c4c7912743d57b82f1a368e3ef4960.
