What this PR does / why we need it:

This is needed because Prow (and so @poiana) matches only against the first slash. Thus labels cannot contains other slashes.
There was a mismatch between the PR template and the labels kind/rule-* which I manually fixed (in the future labels will be automated).

Which issue(s) this PR fixes:

Fixes #696
