* Make SlashingSpans Public (#6961)

* Make SlashingSpans Public

Offchain Applications will often need to inspect this type because it is directly used in staking election, thus worthy of being `pub`. Rest of the slashing api can remain private, only this and the `fn last_non_zero_slash()` of `SlashingSpans` are of interest.

* Update frame/staking/src/lib.rs

* client/authority-discovery/src/service: Improve docs (#7059)

* Decrease poll interval (#7063)

Offchain Worker Example Module

The Offchain Worker Example: A simple pallet demonstrating concepts, APIs and structures common to most offchain workers.

Run cargo doc --package pallet-example-offchain-worker --open to view this module's documentation.

Overview

In this example we are going to build a very simplistic, naive and definitely NOT production-ready oracle for BTC/USD price. Offchain Worker (OCW) will be triggered after every block, fetch the current price and prepare either signed or unsigned transaction to feed the result back on chain. The on-chain logic will simply aggregate the results and store last 64 values to compute the average price. Additional logic in OCW is put in place to prevent spamming the network with both signed and unsigned transactions, and custom UnsignedValidator makes sure that there is only one unsigned transaction floating in the network.
