Dynamic date add parameter

[malgorzatagwinner]

Addition of two markers for data ranges. One returns a data range from a given year until now, and another from a given year until last_year. They allow having separate deployment schedules for older years than last_year.

• "years_from_x_until_now_included": e.g. "years_from_2019_until_now_included",
  refers to a date range of the years from a given year
  until the current year included
• "years_from_X_until_Y_years_ago": e.g., "years_from_2019_until_2_years_ago",
  refers to a date range of the years from a given year until last year
  (not including last year)
