Generate runtest/cve from metadata info

[pevik]

@metan-ucw suggested to generate runtest/cve from metadata info could be a first step to move from static runtest files.

@metan-ucw found that it would require to storetest variants (do not confuse with test_variants in the current C API) into the metadata, because some CVE tests have command line options (setsockopt08 -i 100, request_key03 -b cve-2017-15299). The question is how to make this info unique enough, maybe something like extra_opts array.

Instead of putting the info into ltp.json and parsing it again it might be easier create runtest/cve directly in metadata parser while creating ltp.json.
