4ba54ccfca Reorder imports. 
Trying to separate:
1. Stuff for handling the swarm of nodes and generic table data replication
2. Stuff for the object store core application: metadata tables and block management
3. Stuff for the S3 API

db1c4222ce Don't send items... 
...if syncer doesn't need them because he's going to delete the partition anyway.
Also, fix block resync queue

e41ce4d815 Implement getting missing blocks when RC increases 
Issue: RC increases also when the block ref entry is first put by the actual client.
At that point the client is probably already sending us the block content,
so we don't need to do a get...
We should add a delay before the task is added or find something to do.

9c931f5eda Keep network status & ring in a tokio::sync::watch 
advantages
- reads don't prevent preparing writes
- can be followed from other parts of the system by cloning the receiver

3477864142 Fix the Sync issue. Details: 
So the HTTP client future of Hyper is not Sync, thus the stream
that read blocks wasn't either. However Hyper's default Body type
requires a stream to be Sync for wrap_stream. Solution: reimplement
a custom HTTP body type.
