Anas Nashif 70758c4374 tests: fix test identifiers The seasonal overhaul of test identifiers aligning the terms being used and creating a structure. This is hopefully the last time we do this, plan is to document the identifiers and enforce syntax. The end-goal is to be able to generate a testsuite description from the existing tests and sync it frequently with the testsuite in Testrail.
