* Update integrated-storage.mdx

The quorum paragraph shall also be updated with the table:
instead of: 
"A Raft cluster of 3 nodes can tolerate a single node failure while a cluster
of 5 can tolerate 2 node failures. The recommended configuration is to either
run 3 or 5 Vault servers per cluster."

shall be:
"A Raft cluster of 3 nodes can tolerate a single node failure while a cluster
of 5 can tolerate 2 node failures. The recommended configuration is to either
run 5 or 7 Vault servers per cluster."

* Give an explicit node recommendation

A Raft cluster of 3 nodes can tolerate a single node failure while a cluster
of 5 can tolerate 2 node failures. The recommended configuration is to either
run 3 or 5 Vault servers per cluster. This maximizes availability without
greatly sacrificing performance. The [deployment table](#deployment-table) below

### Deployment Table
Below is a table that shows quorum size and failure tolerance for various
cluster sizes. The recommended deployment consists of a minimum of 5 or more servers that are odd in their total (5, 7, etc). A single
server deployment is _**highly**_ discouraged as data loss is inevitable in a
failure scenario.
