This declarative style is simpler to compose than the imperative wiring
up of objects.
+ pass context to StartOnlineServices as parameter. one by one, trying
to remove dependencies on node state so these initialization steps can
be broken down.

d3view is now in its own repo:
https://github.com/jbenet/ipfs-diag-net-d3-vis
This is so we can iterate on it quickly without having to
needlessly waste CI resources.
The repo also installs it for you:
```sh
git clone github.com/jbenet/ipfs-diag-net-d3-vis d3view
cd d3view
sudo make install
```
doh! I forgot to make sure leveldb is only opened once. thanks for catching this @mappum
* You may be wondering why we don't just share pointers to FSRepos. We
want to manage the lifecycle of the FSRepo by tracking its `state`.
Thus each FSRepo/goroutine requires private instance variables. For
this reason, each `fsrepo.At(p)` caller must get its own goroutine.
* There's a test in `fsrepo` because callers desire the ability to Open
from multiple goroutines. There's a test in `component` because this
is where the actual work needs to go in order to provide the desired
contract. If the `component` package moves, the assurances need to
move along with it.

side note: there are a couple packages in FSRepo that it might be
worthwhile to extract once the dust settles on this feature-set.
```Go
e := log.EventBegin(ctx, "provide")
e.Done()
e := log.EventBegin(ctx, "provide")
e.Close() // implements io.Closer in case you want to register with some lifecycle management system.
```
All the datastores used by pinners and so on should be mutex
wrapped. One issue with changing all of them from
ds.Datastore -> ds.ThreadSafeDatastore is that we wrap the
incoming ds.ThreadSafeDatastore with other datastores, which
do not implement the interface. Re-wrapping again causes
double locking. (which may be ok..., but...) any ideas?
