datapath-windows: support meter action initial version
This patch implemented meter action, currently, meter only support drop
method and only support one band. The overall implementation is, when a
packet comes in, it will first lookup meter according to the meter id,
then get the band->rates and delta time since last access the same meter
from the meter struct. Add the multiply result(band->rates * delta_time)
to bucket, finally bucket minus the packet size, if the result larger
than zero, allow the packet go through, otherwise deny the packet go
through.
Test case:
1. Setting the size meter size 3M, then the bandwidth was limit
around 3M;
ovs-ofctl -O OpenFlow13 add-meter br-test meter=2,kbps,\
band=type=drop,rate=3000
ovs-ofctl add-flow br-test "table=0,priority=1,ip \
actions=meter:2,normal" -O OpenFlow13
2. Setting the meter size 8M, then the bandwidth was limit
around 8M;
ovs-ofctl -O OpenFlow13 add-meter br-test meter=2,\
kbps,band=type=drop,rate=8000
ovs-ofctl add-flow br-test "table=0,priority=1,ip\
actions=meter:2,normal" -O OpenFlow13
