* clarify Conditions section in arch/nodes.md
The field name is `conditions` (plural), so have the section name match
the field name. In addition, updates the JSON output of an individual
Condition to match all the fields returned in k8s 1.14+.
* add information about Allocatable to nodes.md
Since k8s 1.6, a Node object returns information about both the node's
capacity as well as the allocatable resources on the node. The latter is
a representation of the resources that are available for normal pods to
consume.
This patch adds information about capacity vs. allocatable to the
documentation about nodes and provides a link to where the reader can
find more information about reserving compute resources.
