The previous method ended up validating the app name when checking if the app was deployed or not, which isn't necessary as that should only be performed at the command-level.
Some things must pull *all* apps vs filtered apps (mostly things that write out config files or install triggers). Using an unflitered list is best.
Also, we default to filtering, which should be what most usage needs.
Previously, checking if an app was deployed actually checked if there were any running processes. This is not only incorrect, but also fails to take into account applications that do not have running processes and are only used for one-off commands.
This fix migrates apps to the new "deployed" property which is set in core-post-deploy. The result is a slightly faster "deployed" check that is correct and allows non-scaled apps to actually work.
Closes#4398
