The operation "Download JOC Cockpit Log" should be visible only with the permission joc_cockpit:view:log being set

Current Situation

• The JOC Cockpit provides a function in the dashboard to download the JOC Cockpit log. This option is available for everybody.

Desired Behavior

• The button to download the JOC Cockpit log should only be available for users that have the permission joc_cockpit:view:log
• By default this permission is assigned the Administrator role. This is reflected in the initial shiro.ini file that ships with JOC Cockpit.
• The documentation from the Permissions for the JOC Cockpit Web Service article should be updated.
• Delivery of the shiro.ini-example file should consider this permission.
