[enhancement] Add the ability to specify a connection name

[SashaYurchenko]

Right now the default name is used which is "Unknown"

It would be nice to set a friendly name for any new connection by passing it in the client properties.

export interface ConnectionParams {
    hostname: string;
    port: number;
    ...
    connectionName?: string;
}

Thanks! This is indeed something we can do, we'll probably bundle this in the next release!
