this change adds the values of ESP.gteMaxAllocHeap() and ESP.getMinFreeHead() to the prometheus metrics and the system information object. the web UI uses these values to diplay the size of the largest free contiguous block, calculate a rough estimate for the level of fragmentation, and the maximum usage of heap memory since boot in absolute and relative amounts.
