Unable to deploy template, due to network existing on different node

[ghost]

Bug description
Trying to deploy a container template with a network that only exists on a single swarm node (different to the one Portainer is running on) fails, as that network doesn't exist where Portainer is trying to deploy the container

Expected behavior
Not sure on the best UX for this.

1. Hide the network if it doesn't exist on the node Portainer is on.
2. Alternatively we could just make the message clear the that the network specified does not exist on the node that portainer is running on
3. Add the ability to specify host and then only show networks of the node selected

Steps to reproduce the issue:

1. Create network test on node2
2. Try to deploy template with this network
3. See error could not find network test

Obviously this is because the network doesn't exist on the node the template is being deployed on
