This is a proposal on how to migrate highfive to triagebot. Triagebot will be updated with the following: Add support to detect r? foo to perform the same behavior as @rustbot assign foo. This is essentially https://github.com/rust-lang/triagebot/pull/433 and https://github.com/rust-lang/triagebot/pull/946. This will only be enabled if the [highfive] table is in triagebot.toml. This requirement makes it possible to transition away from highfive without having the two bots fighting each other (see transition below). This will use the groups and owners configuration from triagebot.toml (see below).
