Subject Passing TransactionId as part of action invocation
Date Thu, 15 Aug 2019 17:19:56 GMT
Currently we pass the `activation_id` as part of `/run` call to any
action runtime [1]. Would it be fine to also pass the `TransactionId`
such that it can be accessed by action code?

One usecase of this would be to enable tracing a sequence/composition
by linking all activations which are part of same transaction in
epsagon [2]
