For now, all segmented devices are treated the same as SEGMENTED. In the future,
there may be different kinds of segmeted devices, like SEGMENTED_NVME, SEGMENTED_SSD,
and even SEGMENTED_SATA. We plan to use a dedicated segment cleaner for each kind of
those devices, and if there are multiple devices of the same kind, they share the same
segment cleaner.

This commit makes Scanner an extent reader that route read requests to the corresponding
backing devices according to the device ids encapsulated in the segment ids.

The current strategy is to inline allocate non-REWRITE extents in order
to reduce the record overhead. The observation shows the transactions
from user is usually very small and doesn't deserve to be written in ool
records, which requires at least a block to store the record metadata.

Use the enhanced create_n_files to dedup code. Also split the large test
into three.

Few things:
- Allow calling fsync on directory (to support async create kernel).
- Allow immediately unlinking the created file (for stray testing).
- Close any file descriptors created.
- Write unique content (the i variable) to each file.

We want the agent to actually report metadata at the rate we set
it for. Before this, that rate was just being used as the wait time
between iterations so the actual time between iterations was the
given interval plus the time to gather metadata. Now the time between
reports should actually be roughly the given interval.

More consistency that way. This also enables us to define the usual
`logger()` function without having a clash with `seastar::logger`.
