Adding Bridges code as git subtree. (#2515)
* Add instructions. * Squashed 'bridges/' content from commit 345e84a21 git-subtree-dir: bridges git-subtree-split: 345e84a2146b56628e9888c9f5e129cb40e868a9 * Remove bridges workspace file to avoid confusing Cargo. * Add some bridges primitives to Polkadot workspace. * Improve docs.

// 1) replace everything with node-template/src/service.rs contents (found in main Substrate repo);

// 2) the only thing to keep from old code, is `rpc_extensions_builder` - we use our own custom RPCs;
