[HDFS-8508] TestJournalNode fails occasionally with bind exception

• Type: Bug

Description

TestJournalNode uses the default port for dfs.journalnode.http-address so it fails occasionally when running with -Pparallel-tests.

The same issue likely exists with other tests. Tests should generate a random port number with retry to reduce the chances of a collision.
