Ferenc Szili 96267960f8 logging: Add row count to large partition warning message ...

When writing large partitions, that is: partitions with size or row count
above a configurable threshold, ScyllaDB outputs a warning to the log:

WARN ... large_data - Writing large partition test/test:  (1200031 bytes) to me-3glr_0xkd_54jip2i8oqnl7hk8mu-big-Data.db

This warning contains the information about the size of the partition,
but it does not contain the number of rows written. This can lead to
confusion because in cases where the warning was written because of the
row count being larger than the threshold, but the partition size is below
the threshold, the warning will only contain the partition size in bytes,
leading the user to believe the warning was output because of the
partition size, when in reality it was the row count that triggered the
warning. See #20125

This change adds a size_desc argument to cql_table_large_data_handler::try_record(),
which will contain the description of the size of the object written.
This method is used to output warnings for large partitions, row counts,
row sizes and cell sizes. This change does not modify the warning message
for row and cell sizes, only for partition size and row count.

The warning for large partitions and row counts will now look like this:

WARN ... large_data - Writing large partition test/test:  (1200031 bytes/100001 rows) to me-3glr_0xkd_54jip2i8oqnl7hk8mu-big-Data.db

Closes scylladb/scylladb#22010
