Integrate member repository details using the CN node capabilities service

[csjx]

Each member repository has its own node capabilities document that gets updated on the Coordinating Node using the CN.updateNodeCapabilities() call. An example node document is https://cn.dataone.org/cn/v2/node/urn:node:ARCTIC (be sure to view the XML source). On the CN, the node documents have a number of CN-managed properties, like:

<property key="CN_operational_status">operational</property>
<property key="CN_date_operational">2016-12-01T00:00:0.000Z</property>
<property key="CN_node_name">Arctic Data Center</property>
<property key="CN_logo_url">https://raw.githubusercontent.com/DataONEorg/member-node-info/master/production/graphics/web/ARCTIC.png</property>
<property key="CN_date_upcoming">2016-04-05T00:00:0.000Z</property>
<property key="CN_info_url">https://arcticdata.io/</property>
<property key="CN_location_lonlat">-119.69,34.42</property>

Change the DataONE homepage to pull the logos and other node information directly from this service using the either the CN.listNodes() call or the CN.getNodeCapabilities(nodeid) call.

By doing this, member repositories can update their information and it will propagate to the DataONE site.

We may be able to reuse code from the existing DataONE site.

It should be easy to send an XHR to the CN node service, then use jQuery to $.parseXML() to convert the info to json.

Just a side note: The ability to use XML data in Hugo templates is on Hugo's development road map (see gohugoio/hugo#4470). Once that feature is implemented, we could perhaps integrate member repository details like this.

And we can also think about using the browser's internal Fetch API, which reduces our dependency on JQuery. that said, we'd have to figure out a polyfill for older browsers, so, something to consider.

All this info is fetched and parsed by MetacatUI, so I've been thinking we should just create a view in MetacatUI for this and link to that page from dataone.org. Thoughts?
