All of the tests defined in the guidelines should be prefixed by
"id-" for 2 reasons:
1. it's a pattern which has been already set with tempest tests -
ids of tempest's tests aren't prefixed with "id-" in tempest,
however, they are in the guidelines.
2. tools/consistency.sh will fail otherwise - tools/checktest.py
adds the prefix to every discovered test [1] - due to the fact
number 1. (although I'm not sure what was first and why the
uuids are prefixed in the first place). If the uuids in
a guideline aren't prefixed, the consistency check will fail.
