Collector slabinfo (#6800)
### Summary Provide new collector parsing `/proc/slabinfo` to provide details on kernel slab structures. Asked by issue #13 (very happy for the oldest issue in backlog) ##### Component Name collectors/slabinfo.plugin ##### Additional Information This slabinfo details allows to have clues on actions done on your system. In the following screenshot, you can clearly see a `find` done on a ext4 filesystem (the number of `ext4_inode_cache` & `dentry` are rising fast), and a few seconds later, an admin issued a `echo 3 > /proc/sys/vm/drop_cached` as their count dropped.
