Throw exception if replication is not enabled on the remote domain

[varunsrivathsav]

Description

If replication is installed on the remote domain, currently the start API fails with ActionNotFoundTransportException. This CR is to surface an explicit message to say that the remote does not have replication enabled

Testing

Tested it on a setup with remote cluster without replication artefacts.
