Tomasz Grabiec 266a225416 utils: avoid exceptions in disk_space_monitor polling loop ...

The poll loop used condition_variable::wait(timeout) to sleep between
iterations. On every normal timeout expiry, this threw a
condition_variable_timed_out exception, which incremented the C++
exception metric and triggered false alerts for support.

Replace the timed wait with a seastar::timer that broadcasts the
condition variable on expiry, combined with an untimed wait(). The
timer is cancelled automatically on scope exit when the wait is woken
early by trigger_poll() or abort.

Fixes SCYLLADB-1477
