If leader halts too quickly, followers might not be able to pick up
the config change soon enough. This CR introduces a delay before
halting the chain on leader.

This commit moves code which takes care to free resources and stop peers
and orderers processes after the integration test. Also need to make
sure system channel is actually ready to pull configuration blocks, by
actually waiting for leader to be selected.

This CR bundles four small serviceability fixes for Raft.

1) It removes the newlines from a log message which made it difficult to
consume and appeared to create a truncated list like this:

 INFO 17155f Entering, channel: testorgschannel1, nodes: [ID: 3

2) It adds periods to all of the metric definitions in the cluster
metrics.

3) It converts the message send time in the cluster package to be
seconds and clarifies the description with the unit 'seconds'.

4) It clarifies that the number of leader changes is what this process
has observed since start, and not the total number of leader changes for
the network.

The docs currently have many references to the ports
for the peers (the ports *inside* the Docker network).
I changed these ports recently, so here are the doc
updates to reflect these port changes.

BYFN has the following port mappings:
peer0.org1.example.com - 7051
peer1.org1.example.com - 8051
peer0.org2.example.com - 9051
peer1.org2.example.com - 10051
peer0.org3.example.com - 11051
peer1.org3.example.com - 12051

There is a regression caused by https://gerrit.hyperledger.org/r/27558


where the error caused by connection failure to CouchDB does not get handled.

This leads to a nil pointer panic when the nil vdbProvider tries to get
a handle to a database.

This change will handle the CouchDB connection error gracefully and panic
the peer with a good error message (e.g. connection problem,
username/password problem) as was done in prior releases.
