WAL: better errors and new fail point (#3246) 
* privval: more info in errors

* wal: change Debug logs to Info

* wal: log and return error on corrupted wal instead of panicing

* fail: Exit right away instead of sending interupt

* consensus: FAIL before handling our own vote

allows to replicate #3089:
- run using `FAIL_TEST_INDEX=0`
- delete some bytes from the end of the WAL
- start normally

Results in logs like:

```

Notice the EOF, the step regression, and the conflicting data.

* wal: change errors to be DataCorruptionError

* exit on corrupt WAL

* fix log

* fix new line
