Is it possible to write a system test showing the interface configuration? Perhaps this could fall into the cluster topology tests? |
…r the dedicated channels or channel templates.
…oid an ad hoc channel creation and re-use the `interface` param and the `media` of the source channel.

This PR makes it possible to configure
interfaceparams for all of the Cluster channels. To that end it:ChannelUri#createDestinationUri.aeron.cluster.follower.catchup.channelandaeron.cluster.leader.archive.control.channel. The former is used to create the replay channel when doing a catch up on the follower node. And the latter is used for creating a control request channel to the leader archive.egressChannelconfiguration option to theConsensusModulewhich is using the same configuration property as theAeronCluster(i.e.aeron.cluster.egress.channel). When theegressChannelis not defined then response channel from the leader to the client is based on theresponseChannelsent by the client. However if it defined then it is used a basis for the response channel, i.e. if the clientresponseChannelcontains anendpointparameter then it will be used to set/substitute the value in theegressChannelof the leader node and otherwise leader'segressChannelis used as is.
