[Config] Add Sanitizing field names

[jackshirazi]

Classic agent link

• https://www.elastic.co/guide/en/apm/agent/java/current/config-core.html#config-sanitize-field-names

What it does

Allows a list of wildcard patterns of field names which should be sanitized. Applies to HTTP headers and application/x-www-form-urlencoded data and queues (JMS, RabbitMQ, SQS, kafka)

Implementation difficulty, location, and dynamism

• Need to do this in the exporter.
• Currently the upstream agent only has db santization. https://opentelemetry.io/docs/zero-code/java/agent/configuration/#db-statement-sanitization
• It can be contributed upstream
• It can be dynamic
