about: updating Hoppr plugin to support HopprCop offline mode

Is your feature request related to a problem? Please describe

The offline mode of HopprCop was not strictly validated with the Hoppr plugin use case. It also was not updated to allow for enabling offline mode. This could be a useful as Hoppr can support execution in an air-gapped environment and theoretically it would be nice to run HopprCop with it.

Describe the solution you'd like

Hoppr Plugin in HopprCop can support the offline mode.
