The `lustrestat` collector reads from the procfs stat files for Lustre like `/proc/fs/lustre/llite/lnec-XXXXXX/stats`.
Metrics:
* `read_bytes`
* `read_requests`
* `write_bytes`
* `write_requests`
* `open`
* `close`
* `getattr`
* `setattr`
* `statfs`
* `inode_permission`
* `lustre_read_bytes`
* `lustre_read_requests`
* `lustre_write_bytes`
* `lustre_write_requests`
* `lustre_open`
* `lustre_close`
* `lustre_getattr`
* `lustre_setattr`
* `lustre_statfs`
* `lustre_inode_permission`
* `lustre_read_bytes_bw` (if `send_derived_values == true`)
* `lustre_write_bytes_bw` (if `send_derived_values == true`)
This collector adds an `device` tag.
