Major Description
The new UUID api introduced in https://github.com/apache/trafficserver/pull/736 is great for tracing operations and requests. However, the most useful information for plugin developers, the unique client request id, is not exposed as an api endpoint. People need to understand very well how TrafficServer works internally to generate this value. By not having the API directly exposed, people need to repeat the same code every time they want to generate this unique identifier.
I'd like to add an API enpoint to generate this identifier based in a given http transaction for plugins to use.
This would be the signature:
tsapi const char * TSClientRequestUuidGet(TSHttpTxn txnp);
