Reorganising the repository - external renames and moves (#4074)

* Adding first rough ouline of the repository structure * Remove old CI stuff * add title * formatting fixes * move node-exits job's script to scripts dir * Move docs into subdir * move to bin * move maintainence scripts, configs and helpers into its own dir * add .local to ignore * move core->client * start up 'test' area * move test client * move test runtime * make test move compile * Add dependencies rule enforcement. * Fix indexing. * Update docs to reflect latest changes * Moving /srml->/paint * update docs * move client/sr-* -> primitives/ * clean old readme * remove old broken code in rhd * update lock * Step 1. * starting to untangle client * Fix after merge. * start splitting out client interfaces * move children and blockchain interfaces * Move trie and state-machine to primitives. * Fix WASM builds. * fixing broken imports * more interface moves * move backend and light to interfaces * move CallExecutor * move cli off client * moving around more interfaces * re-add consensus crates into the mix * fix subkey path * relieve client from executor * starting to pull out client from grandpa * move is_decendent_of out of client * grandpa still depends on client directly * lemme tests pass * rename srml->paint * Make it compile. * rename interfaces->client-api * Move keyring to primitives. * fixup libp2p dep * fix broken use * allow dependency enforcement to fail * move fork-tree * Moving wasm-builder * make env * move build-script-utils * fixup broken crate depdencies and names * fix imports for authority discovery * fix typo * update cargo.lock * fixing imports * Fix paths and add missing crates * re-add missing crates
