[FEATURE] Add execution context in transformer

[lws803]

Adds execution context in transformer so that we can set sentry scope properties based on what's available in the execution context. e.g. setting a query param from request context as a sentry tag

Should be 9.1.0 as its a feature and not a bug fix[1]. But we can fix this later.
