fix: Add require_installed decorator to FreeBsdIP methods for interfa…

[adrianlasota]

This pull request introduces a new decorator to ensure that IP-related operations on FreeBSD network interfaces are only performed when the interface is installed. The decorator is applied to several methods in the FreeBsdIP class, and corresponding unit tests are added to verify this behavior.

Decorator for interface installation state:

• Added a require_installed decorator in freebsd.py to check if the network interface is installed before executing key IP management methods. If the interface is not installed, an IPFeatureException is raised.
• Applied the @require_installed decorator to the following methods in FreeBsdIP: get_ips, add_ip, del_ip, enable_dynamic_ip, set_ipv6_autoconf, has_tentative_address, wait_till_tentative_exit, and get_ipv6_autoconf, ensuring these operations cannot proceed on uninstalled interfaces.

Testing:

• Added a unit test (test_installed_wrapper) to verify that attempting to add an IP address to an uninstalled interface raises the expected IPFeatureException.

Pull request overview

This PR adds validation to ensure that IP-related operations on FreeBSD network interfaces can only be performed when the interface is installed. A new decorator enforces this check across multiple methods, preventing operations on uninstalled interfaces.

Changes:

• Introduced a require_installed decorator that validates interface installation status before executing IP management methods
• Applied the decorator to eight methods in the FreeBsdIP class: get_ips, add_ip, del_ip, enable_dynamic_ip, set_ipv6_autoconf, has_tentative_address, wait_till_tentative_exit, and get_ipv6_autoconf
• Added unit test to verify the decorator raises IPFeatureException when attempting operations on uninstalled interfaces
