Use multiple ttp templates with multiple commands

[hanunes]

At the moment it's not possible to pass an array of commands to getconfig endpoint, and match multiple ttp templates to the output, meaning that you can't effectively parse data correctly. When you try to do this, only the first command get's parsed correctly.

Would this be too hard to implement?

For now the best thing to do would be use a netpalm script inside netpalm or a service and trigger multiple calls via the netpalm manager class

Basic example https://github.com/tbotnz/netpalm/blob/master/netpalm/backend/plugins/extensibles/custom_scripts/hello_world_advanced_using_netpalm_manager.py

Would these multiple calls trigger multiple device connections? Cause I'd love the ability of taking all the output on just one connection.
