Add new virsh command line `nodecachestats` to expose the cache usage on a node.
Testing:
Setup: one guest with 3072 bytes reserved for it.
Test-1: start libvirt with free cache. resctrlfs default: L3:0=fffff;1=fffff
# LD_LIBRARY_PATH=/root/git/libvirt/src/.libs/ ./virshnodegetcachestats ret=0 nparams=10 L3.0: 13824 L3.1: 13824
The program does: ret = virNodeGetCacheStats(conn, ptr, &nparams, 0); fprintf(stdout, "ret=%d nparams=%d\n", ret, nparams); w = ptr; for (i=0; i<nparams; i++) { printf("%s: %d\n", w->field, w->value); w++; }
