This change introduces a dedicated ConnectionManager for every RemoteClusterConnection such that there is not state shared with the TransportService internal ConnectionManager. All connections to a remote cluster are isolated from the TransportService but still uses the TransportService and it's internal properties like the Transport, tracing and internal listener actions on disconnects etc. This allows a remote cluster connection to have a different lifecycle than a local cluster connection, also local discovery code doesn't get notified if there is a disconnect on from a remote cluster and each connection can use it's own dedicated connection profile which allows to have a reduced set of connections per cluster without conflicting with the local cluster. Closes elastic#31835

You could pass the default "remote connection profile" in as a ctor argument.

Also some whitespace issues here.

as connectionListener.listeners is a CopyOnWriteArrayList, you can use addIfAbsent, which also has proper concurrency semantics

This change introduces a dedicated ConnectionManager for every RemoteClusterConnection
such that there is not state shared with the TransportService internal ConnectionManager.
All connections to a remote cluster are isolated from the TransportService but still uses
the TransportService and it's internal properties like the Transport, tracing and internal
listener actions on disconnects etc.
This allows a remote cluster connection to have a different lifecycle than a local cluster connection,
also local discovery code doesn't get notified if there is a disconnect on from a remote cluster and
each connection can use it's own dedicated connection profile which allows to have a reduced set of
connections per cluster without conflicting with the local cluster.
