5b4debfd81 Improve volume chapter 
In a few places, we were using 'Persistent Volume' the
wrong way. This was fixed.

Also added a whole chapter showing how to use local
persistent volumes, with an actually persistent
Consul cluster.

9fa7b958dc Update Consul demo to use Cloud auto-join 
Consul 1.4 introduces Cloud auto-join, which finds the
IP addresses of the other nodes by querying an API (in
that case, the Kubernetes API).

This involves creating a service account and granting
permissions to list and get pods. It is a little bit
more complex, but it reuses previous notions (like RBAC)
so I like it better.

There is no significant change to the *content* here, but a lot
of typo fixes and commands added so that the autopilot works
correctly.

defeef093d Add dynamic provisioning and PostgreSQL example 
In this section, we setup Portworx to have a dynamic provisioner.
Then we use it to deploy a PostgreSQL Stateful Set.
Finally we simulate a node failure and observe the failover.
