As a cluster admin I want to set a cluster wide setting for hiding the Lightspeed button from OCP Console, for all the console users. This change will need to consume api and console-operator changes done in CONSOLE-4161.  Console need to read the new field `LightspeedButtonState` field and set it as a SERVER_FLAG so frontend will be able to digest it. 

AC:

• Extend the bridge flags with the `LightspeedButtonState` flag
• Add ability to read the field directly from console-config.yaml 
• Pass the field to the SERVER_FLAGS
• Add proxy to console backend though with we would check availability of lightspeed-operator PackageManifest
• Update Console's RBAC to be able to GET the lightspeed-operator PackageManifest [operator change]
