Currently, unless doing Join() (--bootstrap), we do not connect to any peers on startup.
We however loaded up the peerstore file and Raft will automatically connect
older peers to figure out who is the leader etc. DHT bootstrap, after Raft
was working, did the rest.
For CRDTs we need to connect to people on a normal boot as otherwise, unless
bootstrapping, this does not happen, even if the peerstore contains known peers.
This introduces a number of changes:
* Move peerstore file management back inside the Cluster component, which was
already in charge of saving the peerstore file.
* We keep saving all "known addresses" but we load them with a non permanent
TTL, so that there will be clean up of peers we're not connected to for long.
* "Bootstrap" (connect) to a small number of peers during Cluster component creation.
* Bootstrap the DHT asap after this, so that other cluster components can
initialize with a working peer discovery mechanism.
* CRDT Trust() method will now:
* Protect the trusted Peer ID in the conn manager
* Give top priority in the PeerManager to that Peer (see below)
* Mark addresses as permanent in the Peerstore
The PeerManager now attaches priorities to peers when importing them and is
able to order them according to that priority. The result is that peers with
high priority are saved first in the peerstore file. When we load the peerstore
file, the first entries in it are given the highest priority.
This means that during startup we will connect to "trusted peers" first
(because they have been tagged with priority in the previous run and saved at
the top of the list). Once connected to a small number of peers, we let the
DHT bootstrap process in the background do the rest and discover the network.
All this makes the peerstore file a "bootstrap" list for CRDTs and we will attempt
to connect to peers on that list until some of those connections succeed.
As follow up to #787, this uses the default libp2p connection manager for the
cluster libp2p host. The connection manager settings can be set in the main
configuration section (but it should be compatible with previous
configurations which have it unset).
This PR is just introducing the connection manager. Peer connection
protection etc will come in additional PRs.
For simplicity, I haven't exposed the entire
badger config. Also, due to go default values and
the badger implementation, I have had to extract the
two loading mode config values so we can determine
whether it has actually has been set by the user in
the json config file.

This fixes multiple issues in and around tests while
increasing ttls and delays in 100ms. Multiple issues, including
races, tests not running with consensus-crdt missing log messages
and better initialization have been fixed.

IPFSConnector Pin operation should not have a timeout since the start
of the operation, but a timeout since the last block was received,
thus only cancelling operations when there are no more blocks provided
in the network
* Fix error messages (they must be in the form "doing something")
* Improve/reword some error messages
* Document the identity.json existance in the cli docs
* Fix a bunch of typos
* Fix missing folder path in the --help
* Fix cluster not locking when configuration is not there but folder is
* Fix force flag not overriding the config overwrite prompt
* Fix deletion of Raft state on re-init (not necessary if identity persists)
* Fix overwriting on identity (should not be overwritten if already exists)
Much of this paves the way to be able to run without service.json:
* Either taking default values (and using env vars) - maybe someday
* Either by getting a configuration template it from somewhere (ipfs, http)
at runtime - sooner.
