There is now one SEVSNPVersions type that has a variant
property. That property is used to build the correct JSON
path. The surrounding methods handling the version objects
are also updated to receive a variant argument and work
for multiple variants. This simplifies adding AWS support.
The cli now takes CSP and object kind as argument.
Also made upload an explicit command and the report
path/version an argument.
Previously the report was a flag. The CSP was hardcoded.
There was only one object kind (snp-report).
