Copy Configuration Mount

• Issue is based on frontend#194

Description

The goal is to provide the possibility that a user can copy an existing mount of a configuration. This would improve the work with mounts, because the user no longer has to build a mount tree for every setup.

Acceptance criteria

• possibility to search for a mount setup by configuration and date
  • several filter options like the extended search of configuration page
• a preview of the selected mount setup
• possibility to set mount and unmount date for the new setup
• possibility to edit the mount information for each mounted entity
  • offsets and contacts of the original mount setup should be defaults, but not: real world locations, labels, descriptions
• overview of the mounts that will be created
• it should be possible to be able to copy a selection of the mount tree
• it should be possible to exchange single devices/platforms
