Improve submission support for applications that have required submission parameters

[natashadsilva]

When submitting a job with a parameter whose value you wish to or have to set, the job must be submitted from the Streams Console. Perhaps there is no way to specify a parameter from Atom, but the user should be told what to do.
I get this error:
CDISR1146E The following job submission parameter is required, but it is missing: my.name.space::MyMainComposite.list1.

Which a new user would not know how to fix. One suggestion is to check for the specific error code and then let the user know that the job must be submitted from the Console.

@guychris This is applicable to all submission parameters, not just required ones. Ones with defaults should have the option to set the value on a submit.
