Initial approach follows Ecto instrumentation, recording spans for all
Redix `[:redix, :pipeline, :stop]` events.
The command sanitization is inspired-by and adapted from [Java
instrumentation][1], from where I've also copied the actual commands and
what configuration should they follow.
Network attributes are tracked via a "sidecar" process, which keeps
track of connection attributes also via `telemetry`. This extra bit of
bookkeeping is needed as command events doesn't include that piece of
information, unfortunately.

By default a new trace is automatically started when a job is processed
by monitoring these events:
* `[:oban, :job, :start]` — at the point a job is fetched from the database and will execute
* `[:oban, :job, :stop]` — after a job succeeds and the success is recorded in the database
* `[:oban, :job, :exception]` — after a job fails and the failure is recorded in the database
To also record a span when a job is created and to link traces together
`Oban.insert/2` has to be replaced by `OpentelemetryOban.insert/2`.
Before:
```elixir
%{id: 1, in_the: "business", of_doing: "business"}
|> MyApp.Business.new()
|> Oban.insert()
```
After:
```elixir
%{id: 1, in_the: "business", of_doing: "business"}
|> MyApp.Business.new()
|> OpentelemetryOban.insert()
```

* Set error status on error instead of just adding attribute
* Use Exception.message if error is an exception

As it stands, when source is nil (which, for example, can happen if there is a
call to `Repo.transaction`), the name of the span ends in an odd ':'. This
removes that ':'.
