feat(sql): log the size of executions when they complete

to make changes in size over time more observable.  This makes it easier to see the impact
of features like the artifact store.

Not setting the size in RedisExecutionRepository because the extra
objectMapper.writeValueAsString is potentially expensive and I'm not sure how many folks
are using redis for this.
