Energy Dashboard - Offset Dates

Request:

  1. Add a config item Offset the month to a specific day of the month

  2. Add a config item Offset the start of the 1st quarter to a specific date

  3. Failing the above can date picker be modified to allow for the above

  4. Add an offset for the utility meter so it resets on a specific day of the month rather that the 1st of the month.

  5. Add and offset for the quartly reset so the 1st qtr does not start in jan 1

Reason
My power billing is done per quarter however the 1st quarter begins in Feb 20.
This is also a problem with the meter reset cycles however i get around this using a mix of template sensors and autmations to reset the meters.

As my billing begins on the 20th of the month I am no easily able to compare the data to my bill or view it in a way that relates to my bill
