 Adding a custom active authority means increased effort for the backend, and with a stateful one also the need for more storage. Proposed transaction fees:
 - `install_custom_active_authority`: Tied to the duration of the custom active authority. 
 Normal accounts can only create custom active authoritites with a duration of maximum 1 year. LTM can do any duration and also unlimited, but the transaction fee is capped at duration of 2 years.
-- `update_custom_active_authority` and `delete_custom_active_authority`: Similar to `account_update`
