Introduction of Utility due date field

[RoiJS]

Currently, due date for electric and water bill is always the same with the statement of account which turned out to be not true in all cases because the contract can always start anytime of the month but not with the electric and/or water bills because this usually given end of the month.

This issue will introduced new field on statement of account details page where user can select the due date for the utility bills. Setting the date automatically cannot be done since the date where utility bills are given is unpredictable from within the app so we will make the user pick the date themselves.

TODO:

• Introduce new field DueDate on AccountStatement, AccountStatementWaterAndElectricBillUpdateDto classes
• Update AccountStatementService.updateWaterAndElectricBillAmount() function to add dueDate parameter.
• Update both contract-account-statement-information.component.tns.ts and contract-account-statement-information.component.tns.html to introduce new due date field.

DONE

New setting Utility Bills Due date has been added.
