Closes #9766
This change adds
SHOW STATS FOR 'indexes'which returns an estimate of memory use of all indexes. Index memory use is not reported withSHOW STATSbecause it is a potentially expensive operation, and the implementation ofSHOW STATSis also triggered every 10s to populate the_internaldatabase.Tested by comparing the output of this new function to the heap pprof. Results are comparable, not perfect, but pprof doesn't hold absolute truth either.
