util.openmetrics: Prettify format of histogram buckets
"%g" turns 1GB into 1.07374e+09, which is a bit awkward for the bytes
measurements IMO. Turning up the precision, at "%.17g" turns 0.1 into
0.10000000000000001 while "%0.16" gives 0.1, hiding most of those pesky
floating point artefacts. Lua version 5.2 uses "%.14g" ( see
LUA_NUMBER_FMT in luaconf.h.html ) so it seems like a sensible choice
here.
