feat: make sensitive log value redaction text configurable

[aarmam]

This pull request introduces feature to configure sensitive log value redaction text. Current redaction text "Value is sensitive and has been redacted. To see the value set config key "log.leak_sensitive_values = true" or environment variable "LOG_LEAK_SENSITIVE_VALUES=true"." is too long and takes considerable amount of log space.
