Create Lightspeed hover button as part of core but extensible by Lightspeed Dynamic Plugin

• We need the lightspeed hover button to become part of the core this will help users discover Lightspeed.
• Once a user clicks the hover button the chat window will popup with instructions on how to enable/install lightspeed on the cluster.
• We then need to make this extensible so that the lightspeed team only and can override the existing button and chat window.
• We will not advertise this extension point as we don't want others using it.

AC:

• Check if the PackageManifest for the Lightspeed operator is available on the cluster AND check if the user had permissions to install it
  • If YES, the render the btn
  • If NO,  the render the btn. Once user clicks on the btn the chat box will tell the User to contact Admin and request him to install the Lightspeed Operator
• Add a user-preference to show/hide the hover button. if the 'LightSpeedButtonState' SERVER_FLAG is set to hide, we should not show the user setting.
• The code for the hover btn should be part of the core console
• The hover btn should be an extension point
• LightSpeed plugin will need to use this new extension point
