Threshold Management

As a user, I need to contribute existing threshold configuration via REST API the following contribution example:

ThresholdConfigurator document type should mimic current XML contribution:

<thresholdConfiguration type="File"
                            global="0.88">

      <thresholds>

        <threshold xpath="dc:title"
                   value="0.75"
                   autofill="0.76"
                   autocorrect="0.77"/>

      </thresholds>

  </thresholdConfiguration>

As an Insight Admin
I want to be able to set and change thresholds for every 

So that I can change configurations in different env easily

There should be an area to configure auto enrichment thresholds.
This area should allow to disable/enable bulk auto enrich on each output field. Also, auto-fill and auto-correct thresholds.
These levels should be disable if auto enrich is disable for the field.
It should also be possible to define global and field based thresholds for suggestions.

In order to go to this page, output should have an icon next to it to navigate there.

Technical requirements

Threshold could be substituted with Nuxeo Document and used on runtime. 

A default configuration should be introduced. 

Threshold depends on Document type and assumes global and per property values. 

The ideal solution should have property suggestions.
