[Web] Users: Batch action "Change Quota"

[exalate-issue-sync]

Description

User Stories

• As an Admin I want to edit multiple users quota at once so that I don't have to edit each one by one.

Value

Acceptance Criteria

• Add batch action: "Change Quota" -> Opens modal (c.f. change quota for Spaces)
• If a User is selected who has no quota (ex. guests or not-yet loged in users) the action "change quota" is not available.
• If multiple users are selected of which some have no "Personal", the batch actionshows "Change quota (3)" shows the number the action would be applicable. (not possible because we don't have quota information in the user list, just leave it out)
