-------------------------------------------------------------------
[~ascherbakov] [~nizhikov] The change fixes NPE but not root cause. Root cause,
I believe, is attempt to remove metric configuration on cache stop while it
should be done only on cache destroy.
Cache stop will be performed for example on node stop. After node start cache
will be started too but metric configuration is already removed and will not
applied to the cache metrics.
