Add cloud labels to groups

[ericmittelhammer]

• Gets all of the cloud attributes (currently, those prefixed with label.) within each account from SystemSample via keySet()
• adds them to the NerdGraph SystemSample query so they will be part of each Instance's data.
• adds them Globally to the Group By dropdown

Nice work @ericmittelhammer thanks for this PR. I think this also lays some foundations to doing filtering by tags too 😄
