ce05d0c9b0 Validate utf-8 in string fields (#5607)
## What changed?
Explicitly validate utf-8 in string fields in proto messages in grpc
requests/responses and deserialized from persistence, sampled based on
dynamic config. Optionally fail grpc requests + deserialization also.

Currently the grpc interceptor is on the frontend only. Deserialization
checks are on all services.

## Why?
Part of migrating from gogoproto, which did not validate string fields
as utf-8: before starting to fail requests and deserialization, we want
to monitor for bad data first.

## How did you test it?
unit test, also manual testing with bad data in grpc requests

## Potential risks
This code is potentially slow and runs as a grpc interceptor, could add
cpu load + latency. The sampling control should mitigate this risk.
