Add sanity check for idempotent id's in tempest tests

Idempotent id's for tempest tests must be unique, as it's used to trace
tests even in the event of refactors [1].

This patch adds a new check using check-uuid tool from tempest to
validate id uniqueness. This adds a new test-only dependency to pull in
tempest from PyPI to make pep8 tox target work.

Also, the duplicate idempotent id's in our tests have been fixed.
