tape-admin: improve functionality

Browse Source 
* show UTC in in verbose messages of function calls
  that is the format of date string in the JSON file
* date_iso_to_seconds: correct date_string
* get_mediapool_retensiondays(): new function
* add_retensiondays(): new function
* get_retensiondays(): new function
* update_mediapool_retensiondays(): new function
