Module storage 

Mempool transaction storage.

The main struct Storage holds verified and rejected transactions. Storage is effectively the data structure of the mempool. Convenient methods to manage it are included.

Storage does not expose a service so it can only be used by other code directly. Only code inside the crate::components::mempool module has access to it.
