Human readable sizes for Webadmin Interface

[mcmilk]

Motivation

During the last dcache hackathon meeting, there was the idea to display the rather large byte values of the web interface in a human-readable way.

Already during the meeting there was a first short version of the implementation. Today I have adjusted a few small things and now ask for a review.

Modification

Replace the old JavaScript code of 'httpd/static/scripts/sorting' with a better working one: https://github.com/White-Tiger/sorttable.js

The JavaScript file 'common.js' could be used for other modifications as well.

Result

Fix sorting of the times in 'ms' within the '/cellInfo' page. Display all sizes in human-readable format instead of MiB. The old and new views can be switched using a button in the top left corner.

Target: trunk
Request: 11.x, 10.x, 9.x
Require-book: no
Require-notes: yes

Some sample screenshots:

Old (broken) sorting of times:

New sorting, times are ordered correctly:

Old view in MiB:

New view in MiB, GiB, TiB, PiB, EiB ... whatever is needed:

Hi @mcmilk. Thanks for the contribution. Before we merge, could you please update that the table headers don't say xxx Space/MiB, as the unit is already displayed next the the value and not always MiB

We won't backport the change to older branches.

We won't backport the change to older branches.

Even not v10.2.x - the Latest Golden Release?

[kofemann]

Usually, we backport only bug fixes or significant performance improvements. This PR updates something that (a) nobody really suffers, (b) might break people's scripts if they scrape web pages.

I will spring this on dev meeting next week
