Run go-ipfs with brave agent version suffix

go-ipfs 0.10.0 shipped with support for running ipfs daemon with custom --agent-version-suffix (https://github.com/ipfs/go-ipfs/pull/8419)

Soon, we will be running our ipfs-desktop nodes with --agent-version-suffix=desktop, and it would be useful to run Brave instances with --agent-version-suffix=brave to have better insight into metrics / DHT distribution / usage patterns.

Agent Version can be read via ipfs id | jq .AgentVersion:

• go-ipfs/0.10.0/ - standalone go-ipfs binary
• go-ipfs/0.10.0/desktop - node managed by IPFS Desktop
• go-ipfs/0.10.0/brave - node managed by Brave

@bbondy @autonome Thoughts? I remember we wanted to do this a while ago, but it was not possible without recompiling go-ipfs. (Now it’s just a runtime flag which we could enable after upgrading Brave to go-ipfs 0.10.0)

Adding QA/Blocked as the above will require a 1.31.x RC which I’m hoping to kick off tonight 👍 We’ll need 1.31.84 or higher. @stephendonner mind doing a quick spot check on the RC once it’s done? Thanks!
