Watch for runtime upgrades and custom events

With uptest cli tool we can subscribe to the latest blocks and check them automatically for a certain event to be triggered. Once uptest finds our user defined event it will return the hash of the block that contains the event.

Create a custom event with event_summary:

let detect_event = event_summary {
        pallet_name: "system".to_string(),
        pallet_method: "setCode".to_string(),
    }; 

Command line client example:

./target/release/uptest -s Sudo sudo_unchecked_weight
Uptest command line tool
Matches: Some("pallet-method-sub")
