> During the cluster installation, the web client would like to be able to have 
> the administrator configure an alert target for use with that cluster. 
> However, because there are many properties that are used to successfully 
> create an AlertTarget, it's likely that the settings originally provided may 
> not work.
> For example, when creating an AlertTarget for SMTP, if the security or port 
> are not valid (or the SMTP server is restricting access to certain IP 
> addresses) then the target won't be able to properly use it.
> We need to be able to allow an AlertTarget to be "tested" before actually 
> creating it in the system. 
> I propose a new endpoint off of targets that can be used to POST to. The POST 
> can contain all of the alert properties that would normally be found on an 
> AlertTarget. The difference is that no target is created; instead a status is 
> returned about whether the target works (and why it doesn't if it failed).
> I would suggest also altering the dispatcher interface to support a new 
> method; something like {{Dispatcher.testAlertTarget(...)}} which will simply 
> exercise the properties of the target to ensure a good connection.
