feat(inputs.sqlserver): Add persistent version store metrics

[crenstrom]

new measurement: sqlserver_persistent_version_store_stats

Summary

Accelerated Database Recovery (ADR) was added in SQL Server version 2019 and utilizes the Persistent Version Store to store data. Usage of the storage grows and shrinks with use. Monitoring the size and usage is helpful for understanding overall database size and use distribution, as well as identifying and troubleshooting ADR-related performance problems.

@Trovalo any thoughts on this? Given it is protected by a version check I assume this is ok, but wanted your thoughts on the actual query and stats collected.

Thanks!

I'll look into it today

[Trovalo]

Everything seems fine to me, even the naming convention is coherent with all the other queries.
I've never used ADR so I don't have an opinion on the metrics collected (but it's just plain numbers, nothing strange)

Thanks @crenstrom
