Add component Rapid7

[dometto]

ResearchCloud now supports component secrets. This will allow us to create a component for the Rapid7 security monitoring agent.

• only use the rapid7 token when provided as a component secret
• only allow the component to be run on UU workspaces
  • this may require passing the organization as a SRC parameter

Another issue is how to get the Rapid7 install script on the workspace. Rapid7 requires us to download a .deb (or equivalent) from their website. Maybe this can be automated, or maybe we'll have to park the .deb somewhere, if this is allowed.
