Issue : Ability to disable Explore more apps options in the site

Summary:

• create Jira site
• the  Explore more apps options is enabled by default
• This cannot be controlled by admins to disable it for users 
• so user can go and download the apps.
• With this https://support.atlassian.com/security-and-access-policies/docs/manage-your-users-third-party-apps/ we can manage the polices but the tab cannot be disabled

Suggestion:

Please give admins the rights to hide it for all users
