Michael Litvak e7dbccd59e cdc: use chunked_vector instead of vector for stream ids ...

use utils::chunked_vector instead of std::vector to store cdc stream
sets for tablets.

a cdc stream set usually represents all streams for a specific table and
timestamp, and has a stream id per each tablet of the table. each stream
id is represented by 16 bytes. thus the vector could require quite large
contiguous allocations for a table that has many tablets. change it to
chunked_vector to avoid large contiguous allocations.
