* Make CLI state pruning optional again The state pruning setting is stored in the database when it is created. In later runs it is fine to drop the `--state-pruning` CLI argument as the setting is stored in the database. The state db will only return an error if the stored state pruning doesn't match the state pruning given via CLI. Recently we improved the state pruning CLI handling and accidentally made the state pruning value always present (as we set some default value for the clap). If we could find out if a user has passed a value or the default value was taken, we could keep the default value in the CLI interface, but clap isn't supporting this right now. So, we need to go back and make `state_pruning` an optional with the default written into the docs. It also adds a test to ensure that we don't break this behavior again. * More docs

License
- Substrate Primitives (
sp-*), Frame (frame-*) and the pallets (pallets-*), binaries (/bin) and all other utilities are licensed under Apache 2.0. - Substrate Client (
/client/*/sc-*) is licensed under GPL v3.0 with a classpath linking exception.
The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.
In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.
