azure: Warn about memory issues

Browse Source 
The nonzero number of memory/memory+Swap usage hits limits may
indicate the possible env instability(crashes, random failures, etc.).

> memory.failcnt		 # show the number of memory usage hits limits
  memory.memsw.failcnt		 # show the number of memory+Swap hits limits
