ENTMQIC-2326 - Allow users to mask passwords

The qdrouterd.conf router configuration file now supports password masking. In addition to entering passwords in clear text, you can now specify either an environment variable or a file to store the password.

When configuring an sslProfile entity, you can now use the password attribute to mask the password for the private key.

Also, when configuring a connector to connect to peer with user name and password authentication, you can now use the saslPassword attribute to mask the password.

ENTMQIC-2353 - Ability to set different connection limits for different users

You can now define connection limits for different user groups in a vhost. Before, you could set the global maximum connection limit for a router, and the maximum connection limit for a vhost. However, this limit was applied to all users within the vhost. Now, in addition to these connection limits, you can also set the maximum number of connections for a user group within a vhost. When set, this limit overrides the vhost connection limit.

ENTMQIC-2410 - AMQ Interconnect crashes with status=11/SEGV

Previously, the qdrouterd process would occasionally crash with the following message:

qdrouterd.service: main process exited, code=killed, status=11/SEGV

The issue has been fixed.

ENTMQIC-1980 - Symbolic ports in HTTP listeners do not work

When configuring a listener in the router with the http option enabled (for console or WebSocket access), the port attribute must be expressed numerically. Symbolic port names do not work with HTTP listeners.

If a listener is configured as:

listener {
    ...
    port: amqp
    http: yes
    ...
}

It should be changed to:

listener {
    ...
    port: 5672
    http: yes
    ...
}
