add state for connected to transport but not transport plugin

[shanejonas]

Is your feature request related to a problem? Please describe. As a developer creating inspector transport plugins, I've come across the need to show the user the connected status of the transport plugin, as well as the transport that the plugin is running across:

in this example the transport plugin is loaded, but the connect of transport-plugin is not connected. this could show maybe a yellow lightning bolt indicating that its "connected to transport but not transport plugin"
