Documentation about Pallet hooks

• OnInitialize hooks are only executed when a code change is detected.

• OnRuntimeUpgrade hooks are mandatorily executed at the very beginning of the block body, before any extrinsics are processed.

• Inherents are always executed before any other other signed or unsigned extrinsics.

• OnIdle hooks are executed after extrinsics if there is weight remaining in the block.

• OnFinalize hooks are mandatorily executed after OnIdle.
