Julien Danjou f3e7d2a611 network: do not emit counter on exists event, fix resource id

We only emit resource counters like "network.create" when the event is not
something like "network.exists", and we now emit it on the resource itself,
not on 'network'.

This fixes bug #1062949

Measurements

Three type of meters are defined in ceilometer:

double: meter; cumulative double: meter; gauge double: meter; delta

Type	Definition
Cumulative	Increasing over time (instance hours)
Gauge	Discrete items (floating IPs, image uploads) and fluctuating values (disk I/O)
Delta	Changing over time (bandwidth)

Here are the counter types by components that are currently implemented:

Compute (Nova)

Name	Type	Volume	Resource	Note
instance	Gauge	1	inst ID	Duration of instance
memory	Gauge	MB	inst ID	Volume of RAM in MB
vcpus	Gauge	vcpu	inst ID	Number of VCPUs
root_disk_size	Gauge	GB	inst ID	Size of root disk in GB
ephemeral_disk_size	Gauge	GB	inst ID	Size of ephemeral disk in GB
instance:type	Gauge	1	inst ID	Duration of instance type
disk.io.requests	Cumulative	request	inst ID	Number of disk io requests
disk.io.bytes	Cumulative	bytes	inst ID	Volume of disk io in bytes
cpu	Cumulative	seconds	inst ID	CPU time used
network.incoming.bytes	Cumulative	bytes	inst ID	number of incoming bytes on the network
network.outgoing.bytes	Cumulative	bytes	inst ID	number of outgoing bytes on the network
network.incoming.packets	Cumulative	packets	inst ID	number of incoming packets
network.outgoing.packets	Cumulative	packets	inst ID	number of outgoing packets

Network (Quantum)

Name	Type	Volume	Resource	Note
network network.create network.update network.exists	Gauge Gauge Gauge Gauge	1 1 1 1	netw ID netw ID netw ID netw ID	Duration of network
subnet subnet.create subnet.update subnet.exists	Gauge Gauge Gauge Gauge	1 1 1 1	subnt ID subnt ID subnt ID subnt ID	Duration of subnet
port port.create port.update port.exists	Gauge Gauge Gauge Gauge	1 1 1 1	port ID port ID port ID port ID	Duration of port
floating_ip	Gauge	1	ip ID	Duration of floating ip

Image (Glance)

Name	Type	Volume	Resource	Note
image	Gauge	1	image ID	Image polling -> it (still) exists
image_size	Gauge	bytes	image ID	Uploaded image size
image_download	Gauge	bytes	image ID	Image is downloaded
image_serve	Gauge	bytes	image ID	Image is served out

Volume (Cinder)

Name	Type	Volume	Resource	Note
volume	Gauge	1	vol ID	Duration of volune
volume_size	Gauge	GB	vol ID	Size of volume
