deploy: move the metrics and log store toggles

Browse source 
Same move as grafana, and the three belong together: they derive from one
switch and a store with no UI is as useless as a UI with no store.

`victorialogs` is the case that shows why the option-path sweep is not
enough on its own. It has **zero** references spelled
`swarm.victorialogs.enable` anywhere in the tree, and four spelled
through `let` aliases (`vlCfg.enable` in the collector, `cfg.enable` in
its own module). A sweep for the path would have reported nothing to do
and left every reader broken.

Prose moved with the code rather than being left behind: the comments in
swarm-required-services.nix that explained why the pair derives together
now sit above the assignments that do it, instead of above the gap where
they used to be.

sensible deployment that takes one and not the other from that
