Render ELN status page better in the docs

[bookwar]

To show the status in the docs we use iframe and include page

https://osci-jenkins-1.ci.fedoraproject.org/job/eln-periodic/lastSuccessfulBuild/artifact/status.html

See https://github.com/fedora-eln/eln-docs/blob/master/modules/ROOT/pages/status.adoc

We should change this logic and render the page dynamically using data from https://osci-jenkins-1.ci.fedoraproject.org/job/eln-periodic/lastSuccessfulBuild/artifact/eln/output/status.json

For example as in https://osci-jenkins-1.ci.fedoraproject.org/job/eln-periodic/lastSuccessfulBuild/artifact/eln/output/status.html/*view*/

I've attempted to fix this but I am stuck on Cross-Origin Resource Sharing issue:

If I build a json file via Jenkins and make it accessible via artifacts, as in https://osci-jenkins-1.ci.fedoraproject.org/job/eln-periodic/lastSuccessfulBuild/artifact/status.txt, I can not access this file from a Java Script on the docs site.
