gateway_mountpoint.desc:
"""When publishing or subscribing, prefix all topics with a mountpoint string.
The prefixed string will be removed from the topic name when the message is delivered to the subscriber.
The mountpoint is a way that users can use to implement isolation of message routing between different listeners.
For example if a client A subscribes to `t` with `listeners.tcp.\<name>.mountpoint` set to `some_tenant`,
then the client actually subscribes to the topic `some_tenant/t`.
Similarly, if another client B (connected to the same listener as the client A) sends a message to topic `t`,
the message is routed to all the clients subscribed `some_tenant/t`,
so client A will receive the message, with topic name `t`. Set to `""` to disable the feature.
Supported placeholders in mountpoint string:<br/>
- <code>${clientid}</code>: clientid<br/>
- <code>${username}</code>: username<br/>
- <code>${endpoint_name}</code>: endpoint name"""
