vmselect: introduce UserReadableError type of error (#2894) 
When read query fails, VM returns rich error message with
all the details. While these details might be useful
for debugging specific cases, they're usually too verbose
for users.
Introducing a new error type `UserReadableError` is supposed
to allow to return to user only the most important parts
of the error trace. This supposed to improve error readability
in web interfaces such as VMUI or Grafana.

The full error trace is still logged with the full context
and can be found in vmselect logs.
