Add App Pool metrics to IIS module (#70)
* Initial attempt at app pool collector * Rename and tweak * Attempt to convert uptime to unix timestamp * Merge app pool metrics with existing IIS modules * Update comments to reference new class * Add state label to CurrentApplicationPoolState metric * Return 0 value metrics for all non-active app states Return 1 for active state * Remove unnecessary float cast * Add calculation for uptime * Convert iis uptimes to unix timestamps and alter help msg * Rename application pool uptime to start_time
