The following patch adds the following missing attributes:
+---------------------------+--------------------------------------+
| Field | Value |
+---------------------------+--------------------------------------+
| provider:network_type | gre |
| provider:physical_network | |
| provider:segmentation_id | 1 |
| router:external | False |
+---------------------------+--------------------------------------+
Not sure if the code style I've used for the attributes is OK though,
I did it so I don't break the 80 col. barrier.
Added also a small test for the new and existing attributes.
The 'connection' accessor in collections and models actually refered to
a subclassed instance of Fog::Service which creates confusion in the
code.
References to 'connection' could have meant the service or the
Fog::Connection held within that service.
This deprecates the connection accessor and replaces it with `#service`
as a read only value. When a collection or model is initalised then
service should be passed.
This commit also updates all the changes to @connection made by
providers in model initialisers since these depending on the presence of
the 'connection' key. The key is still accepted by outputs a warning.
