HADOOP-18800. Bad ipc.client.connection.idle-scan-interval.ms cause resource leaks

[teamconfx]

Description of PR

https://issues.apache.org/jira/browse/HADOOP-18800
This PR adds a non-negative check for the idle scan duration.

How was this patch tested?

(1) Set ipc.client.connection.idle-scan-interval.ms to -1
(2) Run test org.apache.hadoop.ipc.TestIPC#testSocketLeak
The test fails with an illegal argument exception rather than the assertion error mentioned in the issue.

For code changes:

• Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
• Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
• If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
• If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?
