Modernize mempools (#12282)

* mempools to modern module
quick hacky hrstorage port

* port ucd-snmp-mib to Mempools

* Populate DB for ucd
Prep for yaml

* initial yaml attempt

* more complex conversions
fixes to YamlDiscovery, make leading $ optional and allow mib::oid format

* walk full tables and skip values
normalize percentages above 100

* handle precent only ones (specify total as 100)

* Move default polling out of YamlMempoolsDiscovery

* fixes

* Update test data hrstorage should be correct.

* perc_warn for hrstorage

* Host Resources, record buffer, cached, and shared

* Host Resources is always better, don't do both HR and UCD

* fix unix, include warning levels

* variable size

* consolidate skip_values

* define mempools schema

* number instead of integer

* more schema refactor

* one more skip_values reference

* throw error for invalid oid translation
aos6

* a*  and Cisco

* updated test data

* update almost all hrstorage data files

* b*

* c* with test data
use standard cache for hrStorage

* use cache for storage module too

* hand bsnmp properly

* bdcom

* exclude total oid from yaml so it is not polled
May add a way to ignore this behavior and poll it, but I don't know if that is needed.

* automatically handle percent only values

* ciscowlc

* only poll used or free if we have used, free, and total.

* fix skipping

* the dlinkoning
fix find value when value "name" is numeric

* support numeric oids

* dnos/ftos attempt

* I guess we can't filter on total > 0

* edgecos

* e*

* f WIP

* f*

* gwd (aka g*)

* h* + procurve

* i*

* j*

* m*

* support 0% used memory (however unlikely)

* n*

* CISCO-PROCESS-MIB memory, share cache with processors module

* ignore mempools with invalid total

* p*

* quanta

* r*
fix raisecom mibs terribly broken

* s-z

* style fixes

* Move VRP back to PHP and make it actually work

* fix zynos

* update schema

* Update Cisco processor data for description bug fixes

* fix comware processors

* comware mempools with memory size
default precision to 1

* sophos-xg updated data

* hrstorage use ram size for buffers, cache, and shared

* Show memory available instead of free in device overview

* UCD, use same rrd format, store available instead of free in the db.

* Calculate availability for HOST-RESOURCES-MIB

* Convert UCD to standard polling

* rename old rrd files

* initial graph work

* graph WIP

* Graph looking decent

* Graph looking decent for hr

* handle availability mempool
more graph cleanup

* color adjustments

* remove accidental free calculation

* Update test data and fix corner cases

* fis pfsense

* remove ucd_memory graph references
remove unused device_memory graph

* remove unused functions

* set devices with mempools to rediscover to prevent/minimize gaps

* use a subquery

* add overview graph

* port health mempools table

* Update device mempool

* only show overview if multiple

* Don't override user set warn percentages in discovery

* fix missed usage
