Currently deprecations log is only created for the first service, as
indent is incorrect, so log created only when destination
directory does not exist.
Additionally flow changed to include deprications in output_files and
moving verification of directory existance out of
cycle.
We also now interate over unique set of services, as before
common_log_names and a-r-r were containing duplicates.
