TrustedPeers are specified in the configuration. Additional peers
can be added at runtime with Trust/Distrust functions.
Unfortunately we cannot use consensus.PeerAdd as a way to trust a peer as
cluster.PeerAdd+Join can be called by any peer and this calls
consensus.PeerAdd.
The result is consensus.PeerAdd doing a lot in Raft while consensus.Trust does
nothing, while in CRDTs consensus.Trust does something but consensus.PeerAdd
does nothing. But this is more or less consistent.
I cannot have RPCAPIs expose a SvcID() method as gorpc will warn about it not
having the right signature. So I have created an RPCServiceID() method instead.
While right now it is not allowed for the user to overwrite any entries
in the default policy from the JSON, this should be possible (and easy)
in the future.
PeerAdd called RPC endpoints for `LogMetric` and `ConnectSwarms`
remotely. However, I think similar effect can be achieved by calling
these from the Join() function locally.
In particular, ConnectSwarms was called when maybe the joining peer did not
even know about the other peers in the Cluster. Now this is delayed until some
ping metrics have come through.
This prevents accrual failure detection from kicking in too
soon after a cluster has started.

I had thought of this for a very long time but there were no compelling
reasons to do it. Specifying RPC endpoint permissions becomes however
significantly nicer if each Component is a different RPC Service. This also
fixes some naming issues like having to prefix methods with the component name
to separate them from methods named in the same way in some other component
(Pin and IPFSPin).
Resave configuration if identity.json did not exist. This would remove
identity from service.json

The IPFS pin/update endpoint takes two arguments and usually
unpins the first and pins the second. It is a bit more efficient
to do it in a single operation than two separate ones.
This will make the proxy endpoint hijack pin/update requests.
First, the FROM pin is fetched from the state. If present, we
set the options (replication factors, actual allocations) from
that pin to the new one. Then we pin the TO item and proceed
to unpin the FROM item when `unpin` is not false.
We need to support path resolving, just like IPFS, therefore
it was necessary to expose IPFSResolve() via RPC.
