Rudder

We want all table in Rudder web interface to have json data. We started to do that in #4793 and did it in major tables.

We want to extend it to other tables:

• Technical logs
• Event logs
• Change request table

Here the description of #4793:

Datas in Table are static, to update them you have to reload the page, which can be very not user friendly

We should have a way to fetch latest update of the data, and update the table without reloading the page.

I don't know yet what form should take the 'refresh' feature, for now I'll add a Button

Like #4770, That should be done table by table.

There is multiple grade of evolution here (not ordered...):

* Do it with ajax
* angularize it
* make it asynchronous
* update by itself (comet ?)
* cache date so it faster to get informations

Here we are doing it by adding a single button making an ajax call, fetchning new data ang refreshing the table
