Add exec commands to golang CLI as part of #17522 

`bin/alluxio runClass` -> `bin/cli exec class`
`bin/alluxio runTests` -> `bin/cli exec testRun`
`bin/alluxio runUfsTests` -> `bin/cli exec testUfs`
`bin/alluxio runUfsIOTest` -> `bin/cli exec testUfsIO`
`bin/alluxio runHdfsMountTests` -> `bin/cli exec testHdfsMount`
`bin/alluxio runHmsTests` -> `bin/cli exec testHms`
`bin/alluxio runJournalCrashTest` -> `bin/cli exec testJournalCrash`

For command `exec test`, using different `--name` flags can lead to huge difference in other flags and options.
To manage flags and options, currently using different commands for different test types.
