Write debug log that shows up in trace when meta data file is read/saved

Reading/saving meta data files is a rather expensive operation. E.g. if
a request leads to excessive reads of meta data files we want to see
that in the trace. Reading of meta data files e.g. happens on cache
misses (account cache, group cache etc).

Unfortunately VersionedMetaData has no reference to the project name
so we must pass this in from a lot of places.

Example logs:
