This patch include the following fixs:
- fix image name error when docker ps
- fix docker events test failure: use the exact image name for filter
- fix docker build CI test failure due to "docker events" change
Because of change of daemon log behavior. Now we record
the exact Image name as you typed. So docker run -d busybux sh
and docker run -d busybox:latest are not the same in the log.
So it will affect the docker events. So change the related CI

When we tag an Image with several names and we run one of them,
The "create" job will log this event with
+job log(create, containerID, Imagename).
And the "Imagename" is always the first one (sorted). It is the
same to "start/stop/rm" jobs. So use the correct name instand.

Right now we try device removal at the interval of 10ms and keep on trying
till either device is removed or 10 seconds are over. That means if device
is busy, we will try 1000 times in those 10 seconds.
Sounds too high a frequency of deivce removal retrial. All the logs are
filled easily. I think it is a good idea to slow down a bit and retry at
the interval of 100ms instead of 10ms.

During device removal, we are first waiting for device to close() in a tight
loop for 10 seconds. I am not sure why do we need it. First of all we come
here once the umount() is successful so device should be free. For some reason
of device is temporarily busy, then removeDevice() logic retries device removal
logic in a loop for 10 seconds and that should cover it. Can't see why one
more 10 seoncds loop is required before attempting device removal.
One loop should be able to cover all the temporary device busy conditions and
if condition is not temporary then 10 seconds loop is not going to help anyway.
So instead of two loops of 10 seconds each, I am converting it to a single
loop of 20 seconds. May be 10 second loop is good enough but for now I am
keeping it 20 seconds to avoid any regressions.

Currently in device removal path (device deactivation), we wait
for 10 seconds for devive to actually go away. waitRemove().
In current code this is not required. If dm removal task has completed
and one has done the wait on udev cookie, then device is gone and there
is no need to write another loop to wait for device removal.
This patch removes the waitRemove() which waits for 10 seconds after
device removal. This seems unnecessary.

devmapper graph driver retries device removal 1000 times in case of failure
and if this fills up console with 1000 messages (when daemon is running in
debug mode). So remove these debug messages.

There are issues with libdm logging. Right now if docker daemon is run
in debug mode, logging by libdm is too verbose. And if a device can't
be removed, thousands of messages fill the console and one can not see
what's going on.
This patch removes devicemapper.LogInitVerbose() call as that call will
only work if docker was not registering its own log handler with libdm.
For some reason docker registers one with libdm and libdm hands over
all the messages to docker (including debug ones). And now it is up to
devmapper backend to figure out which ones should go to console and
which ones should not.
So by default log only fatal messages from libdm. One can easily modify
the code to change it for debugging purposes.

I have seen a lot of people try to do this and reach out to me on how to mount
/dev/snd because it is returning "not a device node". The docs imply you can
_just_ mount /dev/snd and that is not the case. This fixes that. It also allows
for coolness if you want to mount say /dev/usb.

When working with Go channels you must not set it to nil or else the
channel will block forever. It will not panic reading from a nil chan
but it blocks. The correct way to do this is to create the channel then
close it as the correct results to the caller will be returned.
