the `hanadb_disk_*_size_mb` metrics group doesn't seem to report correct metrics in relation to multiple filesystems. e.g. in a node with the following filesystems reported by `df -BM -T`: ``` Filesystem...

Disk I/O metrics should not report values for multiple partitions on the same device

I think I/O metrics should only be reported per device, not per partition. e.g. ``` hanadb_disk_io_latency_ms{disk="vda",host="stefanotorresi-hana01"} 0.58 hanadb_disk_io_latency_ms{disk="vda1",host="stefanotorresi-hana01"} 0.0 hanadb_disk_io_latency_ms{disk="vda2",host="stefanotorresi-hana01"} 0.0 hanadb_disk_io_latency_ms{disk="vda3",host="stefanotorresi-hana01"} 0.6 hanadb_disk_io_latency_ms{disk="vdb",host="stefanotorresi-hana01"} 0.28 hanadb_disk_io_latency_ms{disk="vdb1",host="stefanotorresi-hana01"} 0.28 hanadb_disk_io_latency_ms{disk="vdc",host="stefanotorresi-hana01"} 0.35 ```...

`hanadb_disk_*_size_mb` metrics all report a line for a non-existing directory for the `ROOTKEY_BACKUP` usage type: e.g. ``` hanadb_disk_total_size_mb{filesystem_type="",host="stefanotorresi-hana01",instance="192.168.123.15:8001",job="hanadb",path="/usr/sap/PRD/HDB00/backup/sec/",usage_type="ROOTKEY_BACKUP"} ```
