Roman Gushchin fbc1ac9d09 tools/cgroup: add memcg_slabinfo.py tool 
Add a drgn-based tool to display slab information for a given memcg.  Can
replace cgroup v1 memory.kmem.slabinfo interface on cgroup v2, but in a
more flexiable way.

Currently supports only SLUB configuration, but SLAB can be trivially
added later.

Output example:
