Allow multiple hosts in an SCP/SSH Task's "host" field

Problem Definition

When running tasks or deploying files it is occasionally required to target multiple servers. Currently Bamboo's ScpTask and SshTask only allow adding ONE hostname. This means that if we need to copy files to a hundred servers, say, we will need to add a HUNDRED ScpTasks.

Suggested Solution

It would be good if multiple hosts could be added to each ScpTask or SshTask.

Workaround

The workaround is to use a ScriptTask that then invokes the multiple ssh or scp commands.
