Add account.created preset variable to Quota tariffs

[nicoschmdt]

Description

This PR adds the account.created preset variable to Quota tariffs, allowing users to consider an account's creation date when defining values to, for instance, grant a discount on the first month.

This variable is injected as a String. Therefore, users need to parse it first: Date.parse(account.created).

How Has This Been Tested?

In a local lab, the billing of two accounts was compared in relation to the amount of VM snapshots each one has.

• User Account: created on 17 Oct 2024 17:36:46, with 3 VM snapshots
• Root Account: created on 24 Oct 2024 13:51:35, with 1 VM snapshot

The base script for the activation rule used was:

today = new Date(); // current date was 24 Oct 2024
daysDiff = (today-Date.parse(account.created))/(1000*60*60*24);

if (daysDiff <= 5 && daysDiff >= 0) {
  20
} else {
  0
}

When daysDiff is less than or equal to 15 both accounts were charged. When daysDiff is less than or equal to 5 only the Root Account was charged.

It was noted that the first Root Account created by ACS doesn't have a creation date so the script was changed to:

today = new Date();
daysDiff = (today-Date.parse(account.created))/(1000*60*60*24);

if (daysDiff <= 30 && daysDiff >= 0) {
  0
} else {
  20
}

In this condition, it was observed that the first Root Account was charged while the others weren't.
