Upgrade an app by specifying its stack name and recipe. By passing "--all"
instead, every deployed app is upgraded. For each apps with enabled auto
updates the deployed version is compared with the current recipe catalogue
version. If a new patch/minor version is available, the app is upgraded. To
include major versions use the "--major" flag. Don't do that, it will probably
break things. Only apps that are not deployed with "--chaos" are upgraded, to
update chaos deployments use the "--chaos" flag. Use it with care.
