To prepare for per block device metrics: - Move BlockDeviceMetrics from logger to Block module. - Define a global buffer to put per device block metrics. Signed-off-by: Sudan Landge <sudanl@amazon.com>
- Add metrics fs an field in Block{} to record metrics per block.
- Remove new() implementation of BlockDeviceMetrics since default
is enough.
- For each block device added, allocate a metrics struct in global
BLOCK_METRICS pool and save its pointer in Block::metrics.
- Use Block's self.metrics instead of the aggregated METRICS to
record per device block metrics.
- Pass self.metrics to finish() and write_status_and_finish() to
record per block device metrics.
