Introduce maturity firmware levels 7.0.6

FortiOS 7.0.6 and later firmware images use tags to indicate the following maturity levels:

• The Feature tag indicates that the firmware release includes new features.
• The Mature tag indicates that the firmware release includes no new, major features. Mature firmware will contain bug fixes and vulnerability patches where applicable.

Administrators can use the tags to identify the maturity level of the current firmware in the GUI or CLI.

Administrators can view the maturity level of each firmware image that is available for upgrade on the Fabric Management page. When upgrading from mature firmware to feature firmware, a warning message is displayed.
