DCE Leases - Cost Center

[rafabnunes]

Is your feature request related to a problem? Please describe.

When I lease an account from pool, I need additional information like "Cost Center". After lease end I´ll get this information "cost center" to send to department responsible that used an account leased.

Describe the solution you'd like
My suggestion when you request an account using the command bellow, would accept the parameter "--cost-center" and store on table "usage".

dce leases create --budget-amount 10.0 --budget-currency USD --email [email protected] --principal-id quickstartuser --cost-center 4500
