Section Number and Name: 

Overview and Setting Global Build Overrides

Describe the issue: 
In overview it states:

It currently supports overriding the forcePull flag on a build strategy to enforce always refreshing the local image during a build by pulling the image from the registry. This ensures that a user can only build with an image that they are allowed to pull. The plug-in can also be configured to apply a set of image labels to every built image.

However in Setting Global Build Overrides it can also modify a nodeSelector, annotations and tolerations.

Suggestions for improvement:
Mention update what can be done in the overview.

Juan -- What do we need to fix here? 

I added links to the "Manually Setting Global Build Overrides" with the values that can be used for overrides. Also, I added the conclusions that Nicolas added to the customer case. What else can we do to clarify this topic?  

Further down you say:
'Regarding BuildDefaults[2] our docs say: "Build pods will only run on nodes with the key1=value2 and key2=value2 labels. Users can define a different set of nodeSelectors for their builds in which case these values will be ignored." This has to be fixed.'
How can this be improved/corrected? 

The customer, Per, asked about the following:
"Defaults will only be applied if the build configuration does not define any key/value pairs for the nodeSelector and also does not define an explicitly empty map value of nodeSelector:{}." from https://docs.openshift.com/container-platform/3.9/dev_guide/builds/advanced_build_operations.html#dev-guide-assigning-builds-to-nodes. What happend when the nodeSelector is null?
Would it make sense to add Nicolas' conclusions to this section also? 

PS. I saw in our docs:
Regarding BuildOverrides[1] our docs say: "Build pods will only run on nodes with the key1=value2 and key2=value2 labels" in both topics.
Should this be "key1=value1" to match the examples in both topics?
For example, <9> in Step 1

How many versions back should the changes be applied? The BuildDefaults and BuildOverrides plug-ins go back to at least 3.2

The changes look good to me.

About how many branches should get this, based on the documentation available, I'm certain until 3.6.
