Nifi-12390 add more jvm metrics to 1.x line

[esecules]

• Add init, committed, max, and used gauges for the non-heap
• Add usage %, max, used, committed, init, and used-after-gc gauges for each GC-specific memory pool
• Add count, memory used, and capacity for each buffer pool
• retain the nifi_jvm_heap_non_usage metric that was renamed in the 2.x line
• ❓ Would these additional metrics require a boolean property to enable them on back-port to 1.x?

I found a way simpler way of doing this using prometheus DefaultExports. Putting back in draft.
