* transactional: Fix some nitpicks
This fixes some nitpicks related to the transactional storage stuff from me. As everything was
merged too fast, here are some nitpicks from me. First, the entire functionality is moved into its
own file to have a clear separation. Secondly I changed the `set_transactional_level` to not take
`Layer` by reference. Besides that I have added some docs etc.
* Add some comment
* Move tests

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.
