[ERROR UX] "...and n others"

from @pempey
> When an error or warning gives a list and overflows(?) in stdout, you should be able to see the entire list in the logs instead of always `...and n others`

@jtcohen6's expectations
- debug-level logs where I can see the full list - probably `logs/dbt.log`, or `--debug` if I want them on stdout
- a verbose flag to "expand" specific warnings (like we have with `--show-all-deprecations` in dbt Core)

### examples

```
error: dbt0227: No column HIGH_PRIORITY__C found. Available are SOURCE.HIGH_PRIORITY_REASON__C, SOURCE.COGNISM_CITY__C, SOURCE.ISPRIORITYRECORD, SOURCE.ABM_TIER__C, SOURCE.FO_INQUIRY__C, SOURCE.HIGH_PRIORITY_TIMESTAMP__C, SOURCE.LEAD_FROM__C ..(and 351 more)
```

```
