so that an admin can see from the task logs which snapshot was rolled
back/created/removed without the need to look into the journal (to which
the admin might not have access to).

noticed while trying to find out, to which snapshot a vm was rolled back
to on a host where i don't have access to the syslog ;)

good idea in general, but wouldn't it be better to log it before
attempting the operation, so that the context is in the task log
irrespective of how a potential error message looks like?
(side note, we might want to think about making the whole snapshot
process a bit more verbose? i.e., log the individual parts as well?)

i'd probably log both

i noticed that i missed doing that for containers .
also for some storages there is already output (e.g. ceph logs the
snapshot progress)
For a v2 i'd do the logging in 'snapshot_create' etc. in AbstractConfig,
that should handle both vms and ct, and there we can print between
phases too
does that sound ok?

logging the end doesn't give you much (if the name is mentioned earlier
already), since the task already has a status, so it's (heavily) implied
;) but it also doesn't really hurt :)
