Add timeout to gradle check jenkins job and test cases if possible

Following up on the comment #2166 (comment)

Is your feature request related to a problem? Please describe.
The gradle check job does not have timeout. Without a timeout, if the job is stuck, it will hold the resources indefinitely hampering other jobs.

If possible, add test cases for the jenkins job.

Describe the solution you'd like
Add a timeout to the jenkins job https://github.com/owaiskazi19/OpenSearch/blob/main/jenkins/jenkinsfile and if possible, test cases.

@bbarani @peterzhuamazon is this already addressed in the new Jenkins setup?
