Add a menu to add and configure new remote kepler servers
Figure 6 (https://kepler-project.org/developers/incubation/kepler-engineering-view-for-reap/engineering-view-plans ) shows Servers (Server1, Server2) in the Scheduled Workflows section on the left on the Workflow Scheduler view. We need a way for a user to add and configure these servers (address, username, password, database name, port, etc). I believe we've discussed extending the Sources (aka Preferences) menu to add an additional tab for this.
When a user clicks on a workflow listed on one of these servers, a new instance of Workflow Run Manager needs to be created and needs to connect to that server to show the runs, and in order to do this, it needs to access these connection parameters.
