Request

Allow for multiplexing for network devices because some network services drop due to security connection limits hit when connecting repeatedly during playbook execution.

Environment

• Ansible 2.15+
• Cisco network device

Specifics

• Customer has set up multiplexing on RHEL devices using the following ansible.cfg

[defaults] transport = ssh 
[ssh_connection] ssh_args = -C -o ControlMaster=auto -o ControlPersist=360 
control_path = /tmp/sockets/control-%%r@%%h:%%p

• However, this does not work for Cisco devices
• this is likely due to network devices using libssh
  ref: https://docs.ansible.com/ansible/latest/collections/ansible/netcommon/libssh_connection.html
• For libssh, I see ssh_args says "ProxyCommand is the only supported argument."
• this seems to be confirmed in the code
