sort storage params for stable helm upgrade

[EladDolev]

subsequent helm upgrade may fail because the StatefulSet allows only handful of changes, and "cockroachdb.conf.store" function may return different output every time

[EladDolev]

any chance somebody can review this ? this thing causes random pod restart on every helm apply...

Seems valid, but i use store config half a year and upgrade never failed

Upgrade should not fail, but may cause unnecessary pods restart
