Allow multi host settings in ssh/scp tasks

Problem Definition

Currently, both SSH task and SCP task allows the task to be executed against a single host.
In case the same operations needs to be carried out against multiple destinations (multinode deployment could be one example) the ssh/scp tasks needs to be duplicated with only difference the host.

It would be beneficial to allow the execution of SSH/SCP task against multiple host from a single task.

Suggested Solution

In the configuration of the SCP/SSH task allow the possibility to insert multiple hosts.

Why this is important

Duplicating the same ssh/scp task for multiple hosts is much harder to manage in case the command/path needs to be updated (the same change needs to be applied to multiple tasks)
