Archive repo

[rachelleahklein]

Hello @xinminlabs,

On behalf of the engineers of the New Relic Ruby agent, thank you for creating this gem to bring Grape tracing to users of the Ruby agent before it was officially supported!

We appreciate your clear messaging directing folks to use the agent now - would it be possible to archive this repo as well, just to prevent any possible confusion about what we support?

Thanks again for all your work.
