chore: make IPFS API static (remove api-manager) (#3365)

- api-manager is gone.
- There is now Storage component that is glorified `{keychain, repo, peerId}` tuple, that one can `async start` and it takes care of repo bootstrapping (which `init` used to do). As per discussion with @achingbrain `init` was mostly there for historical reasons.
- There is now `Network` service component that is glorified `{peerId, libp2p, bitswap}` tuple.
   - All components that depended upon `libp2p` or `peerId` depend on `network` service now.
   - They can do `await network.use(options)` and get tuple when node is started (if it is starting or started) or an exception if start has not been initiated.
   - This way IPFS node is no longer mutated and APIs that depend on node been started throw if called before start.
- lot of TS typings were added to be able to make this changes with more confidence.
- Set of interfaces were added for things like datastore, repo, bitswap
   - create can be passed implementations and it's useful to decouple interface from a concrete implementation.
   - We had no types for those and it helped having interfaces to increase coverage and enable making these changes.
      > I would like to migrate those to other repos, but doing it as would be more effective than having to coordinate changes across many repos.
- circular dependencies between pinmanager and dag APIs are resolved.
