The "Reset Application" command in the Mac App Store debug menu performs
the following steps
- killall Dock
- killall storeagent (storeagent no longer exists)
- rm com.apple.appstore download directory
- clear cookies (appears to be a no-op)
As storeagent no longer exists we will implement a slight variant and kill all
App Store-associated processes
- storeaccountd
- storeassetd
- storedownloadd
- storeinstalld
- storelegacy
