[User Management] User sorting

[LukasReschke]

As an admin, I want to be able to sort users by many attributes, so that I can easily find and update the users I need. I want to sort on:

• Quota usage – high to low, and low to high (as a percent)
• Full Name
• User Name
• Storage Location – where their files are stored (if using LDAP AD, this can be different by user (only if 13 is in use)
• Last active login – the time when the user last logged into the system (only makes sense if 14 is in use)

Acceptance Criteria:
This should simply be done by sortable headers, similar to windows explorer or other file managers – click on the widget to sort up or down by the attribute.

Remarks by Engineering:
I'd propose a switch to handlebars here to make such things easier…

Idea: Also switch the scrollabr to a more intuitive way:

See music app - there is a list of the alphabet instead of a scroll bar. You then just need to click on "c" to go to the elements starting with C. Once we sort by quota usage we could switch from the A-Z list on the right side (as scrollbar replacement) to a list of quoat (0-100% in 5% steps) and then you click on 90% and got to the users that use 90% of their quota. Same maybe for Last login: Possible values are "Today, Yesterday, This Week, THis Month, This Year, Last Year, Never"

Reasonable way to go? This requires a lot of work on in the backend and frontend too, to make it more flexible.
