[SE-2743] Fix pr_watch in OCIM stage, which is often stuck in a retry loop doing GitHub API calls
Created by: fferrin
This PR reduce the scope of the filter used to check for new PR to avoid to many GitHub API calls.
JIRA tickets: SE-2743
Author notes and concerns:
- I set 1 hour to check for PR created over the last hour. This expects that the previous 59 task calls already catch PR created before the last hour. This limit can be changed.
