decorate report for node scan in remote.go with projects information

[vjeffrey]

User Story

as part of #482, we added the projects information to the generated inspec report.
that's great for "traditional" scan jobs.
however, we also have this logic in inspec-agent/remote/remote.go that is used to build an inspec command to be executed via script. this is used for ssm/azure scans (the script is executed directly on the node).
so we need to add the projects information on the config we create here: https://github.com/chef/automate/blob/master/components/compliance-service/inspec-agent/remote/remote.go#L159
a passthrough object was introduced here: inspec/inspec#3874 -- that is how we should attach the projects information to the report

Definition of Done

node reports generated via the remote code path (ssm jobs, for example), have a projects field upon ingestion

Demo Script / Repro Steps

get an a2 instance in ec2
ensure you have a node with ssm privileges
add an aws-ec2 integration, select checkbox to read creds from the environment
select some projects and set up tags so your ssm node will have a project or two associated with it
run a scan job on your ssm node
see ingested report has projects field on it that matches projects field on ssm node
