Add timestamp for the event of making custom distribution

[antonpolishko]

Motivation: When the user switches from linked yaml for <name> service for the custom one, it would be great to store the version of that services-available/<name>.yaml. Later on when the updates for that file occur it would be easier to check if you need to update your custom distribution yaml

Idea is create 'archives' for disabled custom services.

Question is make 'achive' in each distro or project wide?

Ideas:

1. Create like services-archive/<distro-name>/service_<TIMESTAMP>.yaml.
2. Make possible to view diff between achive files.
   or
3. Use local git repository in service-archive to store version of service?
   1.1 Create local repo automatically if is not exist.
