[FLINK-8557][checkpointing] Remove illegal characters from operator dâ¦
## What is the purpose of the change
This fixes the problem that the operator descriptor text is used to
construct the instance directory in RocksDB, but can contain characters that
are illegal for paths in some file systems.
## Brief change log
We replace all illegal characters with underscore before constructing the
path.
## Verifying this change
Check if RocksDB can be used as state backend on Windows.
This change is a trivial rework / code cleanup without any test coverage.
