51d900d187 datastore: swap ConfigVersionCache with digest for change detection
We got the digest available anyway, and it's only 16 bytes more to
save (compared to last_generation and the recently removed last_time,
both being 64 bit = 8 bytes each)

Side benefit, we detect config changes made manually (e.g., `vim
datacenter.cfg`) immediately.

Note that we could restructure the maintenance mode checking to only
be done after checking if there's a cached datastore, in which case
using the generation could make sense to decide if we need to re-load
it again before blindly loading the config anyway. As that's not only
some (not exactly hard but not really trivial like a typo fix either)
restructuring work but also means we'd lose the "detect manual
changes" again I'd rather keep using the digest.

c8322f8a33 config: don't manually track padding size
make ConfigVersionCacheData a #[repr(C)] union to fix its
size and let it transparently `Deref{,Mut}` to its actual
contents

118deb4db8 pbs-datastore: use ConfigVersionCache for datastore
instead of relying on the content of some configs

previously, we always read and parsed the config file, and only
generated a new config object when the path or the 'verify-new' option
changed.

now, we increase the datastore generation on config save, and if that
changed (or the last load is 1 minute in the past), we always
generate a new object
