Douglas Creager d2d01e77e3 cli: Use anyhow and thiserror for errors ... This patch updates the CLI to use anyhow and thiserror for error management. The main feature that our custom `Error` type was providing was a _list_ of messages, which would allow us to annotate "lower-level" errors with more contextual information. This is exactly what's provided by anyhow's `Context` trait. (This is setup work for a future PR that will pull the `config` and `loader` modules out into separate crates; by using `anyhow` we wouldn't have to deal with a circular dependency between with the new crates.)		2021-06-09 16:17:23 -04:00
