Desktop Client: New Release / Update notification

[teon]

Defguard is heavily under development, new core features arriving each month. In order to promote updates we need a way to check if there are new versions available and notify the user. Proposed mechanism:

1. The client on each startup checks the URL: https://pkgs.defguard.net/update/check by POSTing to that URL:
   • product: client
   • client version
   • operating system

and gets in return a JSON with:

• newest version number
• version release date
• release notes URL
• update URL

2. If a new version is available to update there should be a modal with the information returned from the update service

3. There should be a way to disable automatic update checks in the settings: Check for updates (On/Off) - default on.

4. Check for updates:

   • each client launch
   • if client is working >=12h check (every 12h)

5. Documentation

Add to documentation "Client update" section - and inform that during the "check for update" we send to our update service in order to perform check if new version is available:

• operating system
• client version
