Log manager agent

[gsanchietti]

Integrate LMAgent inside NethServer.

The agent will send the logs to a remote log manager: https://nar.nethesis.it

The new module should:

• allow to configure, enable and disable the agent from Cockpit
• allow the delegation of the application
• handle the backup and restore

Also make sure that:

• all Cockpit labels have been translated: https://www.transifex.com/nethserver/nethserver/translate/#it/CockpitLMAgent/410370523?q=translated%3Ano
• update the comps to display the package inside the Software Center

Test case 1

• Install on a clean machine
• Access Cockpit as root user
• Configure the agent
• Verify the agent sends the logs to nar.nethesis.it
• Change the host and the location
• Verify the new configuration has been correctly applied

Test case 2

• After test case 1, access Cockpit as root user
• Go to the application page, disable the agent
• Verify the agent is not sending data to the remote host

Test case 3

• Access Cockpit as root user
• Create a user and delegate the Log manager application
• Logout with root user and login with the non-privileged user
• Verify the user can see and modify the configuration of the agent

Test case 4

• After test case 1, execute a configuration backup
• Restore the configuration backup to a new machine
• Verify the agent automatically starts to send logs to the correct tenant

New requirements:

• rename the software to Cloud Log Manager agent both on the package and inside the Software Center
• remove hard-coded server nar.nethesis.it
• add an option to change the server host
