Use the telemetry calls to handle user "feedback"

[rgrunber]

As a user of vscode-redhat-telemetry, I would like to also record user initiated feedback using the telemetry backend. However, a user requesting to give feedback, filling out the relevant forms, and clicking submit implies they accept having that data collected. Having the data be ignored because they haven't explicitly enabled telemetry seems a bit wrong. It would require the extra step of informing a user they need to enable telemetry for the feedback to be collected. However, they may not wish to do that.

This request would be to have a separate "feedback" API that would not check whether the user has accepted/rejected telemetry.
