tasks: db: change default task_ttl value

Browse Source 
If a test isn't going to use task manager or isn't interested in
statuses of finished tasks, then keeping them in the memory
for some time (currently 10s by default) after they are finished
is a memory waste.

Set default task_ttl value to zero. It can be changed by setting
--task-ttl-in-seconds or through rest api (/task_manager/ttl).

In conf/scylla.yaml set task-ttl-in-seconds to 10.

Closes #15239
