**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** `Schema` currently implements `Eq` but not `Hash`. The latter would be useful for the following reasons: 1. Sometimes it would be helpful if you could stick a `Schema` into a `HashSet`/`HashMap`, e.g. for interning (this is a quite costly way to intern a schema and usually you should use a cheap proxy key, but sometimes this is also the only easy way to intern a schema) 2. Implement `Hash` for a struct that contains a `Schema` for whatever reason. **Describe the solution you'd like** Implement `Hash` for `Schema`. **Describe alternatives you've considered** Not implementing it. **Additional context** - IOx PR where this could be used: https://github.com/influxdata/influxdb_iox/pull/5215 -- This is an automated message from the Apache Git Service.
