runtime : create cloudevents camel component

[lburgazzoli]

We should create a component that support events according to the cloudevents specifications

[lburgazzoli]

Once ready the component should be moved to camel upstream

Looking at the transport spec: https://github.com/cloudevents/spec/blob/v0.1/http-transport-binding.md

Cloudevents supports a request/reply pattern, so we can use it also to "invoke" a remote route e.g. from a function.

We can rely on cloudevents instead of creating a propretary transport for the "lightweight camel client". Wdyt?
