Add ability to SetProperty so that you can set a property without a command

[tcooperma]

Adding an option to SetProperty? to do the equivalent of "echo foobar" where foobar is some string that you generated in Python using WIthProperties or something else. Perhaps this is done with another parameter?

One option is to extend/modify the definition of SetProperty? in buildbot/steps/shell.py. Another possibility would be to use addFactoryArguments on any custom buildsteps.

So basically this would be a step that doesn't run on the client, but just sets a property to a value?

I think SetProperty? could be adapted to do that. Maybe it could do so if command= is omitted, and intead it gets a value= argument? That's just a vague idea.

This would probably be best done a separate step. Perhaps in buildbot.steps.master, since it doesn't involve talking to the slave?
