Hu Bing 4189a117d2 catch lock fail exception in container updater
in process of container update, when locking one container failed,
container updater stops with LockTimeout exception.

it's better for updater server to continue processing
other containers, partitions instead of stop updating.

this path is to catch timeout exception and log it,
then continue processing other containers and partitions.
