LimitConfigTrait

Sets limits to the target exchange type and is expected to be defined at the contract level.

It’s important to note that these limits correspond directly to the max_<OPERATION> i.e. deposit_limit -> max_deposit.

The EIP-4626 spec states that the max_<OPERATION> methods must take into account all global and user-specific limits. If an operation is disabled (even temporarily), the corresponding limit MUST be 0 and MUST NOT panic.
