Create Cloud Synchronization Clients Component for Packages

[baimafeima]

In order to improve software discovery, I'd suggest to introduce a new Cloud Synchronization Clients category in the software center. The following clients could be part of a new Cloud Sync Clients category:

• rclone
• caja-dropbox
• nautilus-dropbox
• megatools
• nextcloud-client
• owncloud-client
• seafile
• seafile-client
• duplicati: T3830
• nutstore: T4810
• CrashPlan: T1444
