Ensure the semantics of context propagation are clear

[mmusgrov]

If you have a microservice A that wants to participate in an LRA and calls microservice B (which does not have specific LRA behaviour) and this calls microservice C (which does have specific LRA behaviour), then B should not need to be annotated with @lra. The spec should be clear that is the defined behaviour.

Reopened.

The always propagate Context Header is counter intuitive and does not allow to call an endpoint which doesn't have the Context header (when one is present)

[rdebusscher]

The proposal is to define a configuration parameter to activate such propagation under all circumstances.

Note, the propagation of the LRA context is ALWAYS perform within an LRA context (JAX-RS method is annotated with @lra except for @LRA.Type.NOT_SUPPORTED as this type means that you do not have an LRA context active)

No Consensus in trying to make this better.
