#### `executeAction(bytes calldata _calldata) external`

Uses a flash loan to repay all debts for a vault and send all collateral in the vault to the owner.

Requirements :&#x20;

* Contract must be unpaused
* Must be called through the `MIMOProxy` `execute()` function
* Targeted vault must have been created by the `MIMOProxy`
