Configurable web transaction name

I'm using Flask framework, and the web transaction name is automatically determined by callable_name of function.
As a result, stakeholders that access NewRelic dashboards cannot understand which endpoint is related to the transaction.

I would like to have the option to configure the web transaction name according to the rule, which more informative and is known by other stakeholders.

I've considered using set_transaction_name but we don't use new relic agent directly in our code, and doing so would not be as clean as having it configured as part of agent initialisation.

It's a feature that we must have in order to be able to handle production failures rapidly (currently we have to lookup the relevant function in our code base which wastes precious time)

Start by tracing how Flask transaction names are derived from callable_name during agent initialization, then compare that path with the existing set_transaction_name behavior. The issue does not name files or tests, so first locate those entry points and review the 16-comment discussion for any agreed configuration rule. Done means Flask transaction names can be configured without requiring application code to call the agent directly.
