Add a "Limited" network connectivity state (#2696)

Browse Source 
Rename the Transient state on connection to Limited. This is more appropriate and also 
doesn't conflict with the transient resource manager scope.

Adds a Limited connectedness state for peers connected to us over Limited connections. 
This allows  users to ignore such peers if they are interested in only peers connected to 
us over Unlimited connections. 

For some peers who disconnect before we sent a Connectedness event, we will now 
only send a Disconnected event.
