[pve-devel] [RFC manager 4/6] ui: storage creation: retention: dynamically adapt max-protected-backups

[Fabian Ebner <f.ebner@proxmox.com>]

depending on the other retention settings and as long as it isn't
dirty (other than from the updating itself). Allow an unlimited number
when keep-all=1 and use the default fall-back to 5 when pruning or
fall-back for retention is configured.

Might be too much automagic, maybe just setting -1 in afterrender and
the never-rendered scenario is also enough? That is, if we even want
the GUI default for creation to be unlimited. Just thought that it
would better fit the keep-all default.
