In case the age action is created by the shared action API, the shared action context of the Testpmd application was not set. In addition, the application handler of the contexts returned by the rte_flow_get_aged_flows API didn't consider the fact that the action could be set by the shared action API and considered it as regular flow context. This caused a crash in Testpmd when the context is parsed. This patch set context type in the flow and shared action context and uses it to parse the aged-out contexts correctly.
